-'''
-Instructions:
-
-Set the data input directory (the LOGS file) to the 'input_dir' variable.
-
-Set the output directory for the generated PDFs to the 'output_dir' variable.
-
-Set the name of the generated PDF files for the 2- and 3-D plots to the 'twoD_plots_output_pdf_name' and 'threeD_plots_output_pdf_name' variables respectively.
-
-The dictionaries 'global_properties_x_axis' and 'multi_line_plots_x_axis' set the X-axis arguments for the generated 2-D plots. The keys:
-    'plot_variable' Sets the X-axis variable. e.g. star_age or model_number.
-    'x_axis_divider' Allows the units of the X-axis to be manipulated. Options are: None, sec, min, hr, day, yr, kyr, myr, gyr. Example: for 'plot_variable':'star_age' setting 'x_axis_divider':'day' will change the X-axis units to days. Set to None if not in use.
-    'x_axis_scale_type' Allows the scale of the X-axis to be set to linear or log.
-    'x_axis_name_for_plots' Sets the X-axis label.
-    'x_axis_ticklabel_format' Sets the style of the X-axis ticklabels. Can be 'plain' or 'sci' or 'scientific'.
-    'y_axis_ticklabel_format' Sets the style of the X-axis ticklabels. Can be 'plain' or 'sci' or 'scientific'.
-
-The dictionary 'global_properties_plots' takes the Y-axis variables to be plotted as keys and the corresponding Y-axis scale types as the key value. These plots are single line plots.
-
-The dictionary 'multi_line_plots' creates plots with multiple lines for the purpose of comparison. This is a nested dictionary. The keys take the plot titles as their arguments.
-The key values take nested dictionaries as their arguments. The nested dictionaries take the Y-axis variables to be plotted as keys, and the corresponding Y-axis scale types 
-as their keys values. There are no limits on the number of key-value pairs that can be given within the nested dictionaries. Multi-line plots are then created with the nested dicts.
-The same multi-line plot can have both linear- and log-scale variables plotted on the same axes if desired by the user.
-
-The boolean 'only_plot_two_D_graphs' only plots 2-D graphs if set to true, and skips plotting the Kippenhahn graphs.
-
-The dictionary 'Kippenhahn_properties' Takes the arguments for the generated Kippenhahn plots. The keys:
-    'x_axis' Sets the X-axis variable. e.g. star_age or model_number.
-    'y_axis' Sets the Y-axis variable. e.g. star_mass or radius.
-    'overlay_history_line' Allows a line from history.data to be overlayed the heatmap. Set to the variable name in history.data,  e.g. 'mass_conv_core. Set to None if not in use.
-    'overlay_history_line_label' Sets the legend label for the overlayed history line (if used). Set to None if not in use. 
-    'overlay_history_line_colour' Sets the colour of the overlayed history line (if used). Set to None if not in use.
-    'y_axis_min_limit': Sets the minimum Y-axis value to start from. e.g if Y-axis is mass, but you want to plot from mass value 0.9 Msun to the surface, set 'y_axis_min_limit': 0.9 
-    'y_axis_max_limit': Sets the maximum Y-axis value to be plotted. e.g if Y-axis is mass, but you want to plot from the core to mass value 0.8 Msun, set 'y_axis_max_limit': 0.8 
-    'format_x_axis' Formats the X-axis ticks to a certain number of decimal places. e.g. 'format_x_axis':3 allows ticks to have 3 decimal places. Set to None if not in use.
-    'format_y_axis' Formats the Y-axis ticks to a certain number of decimal places. e.g. 'format_y_axis':7 allows ticks to have 7 decimal places. Set to None if not in use.
-    'x_axis_divide_by' Allows the units of the X-axis to be manipulated. Options are: None, sec, min, hr, day, yr, kyr, myr, gyr. Example: for 'plot_variable':'star_age' setting 'x_axis_divider':'day' will change the X-axis units to days. Set to None if not in use.
-    'y_axis_divide_by' Allows the units of the Y-axis to be manipulated. e.g. for 'Y_axis':'radius_cm' setting 'y_axis_divide_by':1e-2 will change the Y-axis units to metres. Set to None if not in use.
-    'z_axis_data_min_cutoff' : If any of the Z-axis data elements are less than 'z_axis_data_min_cutoff', then those Z-axis data elements are set to 'z_axis_data_min_cutoff_replacement'. e.g if 'z_axis_data_min_cutoff':0e0 and 'z_axis_data_min_cutoff_replacement':0e0, then any Z-axis data elements below zero will be set to zero. Set to None if not in use.
-    'z_axis_data_min_cutoff_replacement' : Sets the value a Z-axis element will be replaced with if its value is less than 'z_axis_data_min_cutoff'. Set to None if not in use.
-    'z_axis_data_max_cutoff' If any of the Z-axis data elements are greater than 'z_axis_data_max_cutoff', then those Z-axis data elements are set to 'z_axis_data_max_cutoff_replacement'. e.g if 'z_axis_data_max_cutoff':1e2 and 'z_axis_data_min_cutoff_replacement':1e2, then any Z-axis data elements greater than 100 will be set to 100. Set to None if not in use.
-    'z_axis_data_max_cutoff_replacement' Sets the value a Z-axis element will be replaced with if its value is greater than 'z_axis_data_max_cutoff'. Set to None if not in use.
-    'num_y_axis_elements_for_heatmap' The number of data points the Y-axis will have on the heatmap. A greater number will give more resolution to the heatmap.
-    'x_axis_label_heatmap' The label for the heatmaps x-axis. e.g. 'Star Age [day]'.
-    'y_axis_label_heatmap' The label for the heatmaps Y-axis. e.g. 'Mass [M$_{\\odot}$]'.
-    'x_axis_ticklabel_format' Sets the style of the X-axis ticklabels. Can be 'plain' or 'sci' or 'scientific'.
-    'y_axis_ticklabel_format' Sets the style of the X-axis ticklabels. Can be 'plain' or 'sci' or 'scientific'.
-    'color_bar_scheme_heatmap' Sets the colour scheme of the heatmaps colour bar . For matplotlib colours, go to https://matplotlib.org/stable/tutorials/colors/colormaps.html
-
-The dictionary 'Kippenhahn_plots' takes the Z-axis variables to be plotted as the key and the Z-axis scale type as the corresponding key value. 
-
-The dictionary comparing_at_unity_plots compares 2 Z-axis variables and plots the result as a 2 level Kippenhahn plot that explicitly shows the result of the comparison above and below unity.
-The keys take the plot titles as their arguments. The key values take lists as their arguments. The list must contain either 1 or 2 variables to be compared against each other and plotted
-to show the result above and below unity. For example if the key 'plot1' has a value ['v', 'csound'], then a Kippenhahn plot of cell_velocity/cell_sound_speed will be created that compares the result above 
-and below unity. Note that the first list value will be divided by the second list value. A key can also take a list with a single element as a value, this is because some MESA outputs are 
-in comparison form already, such as the profile.data output 'v_div_vesc' which is the direct output of cell_velocity/cell_escape_velocity by MESA. This particular example will take the key-value pair form
-of 'plot2': ['v_div_vesc'].

-Instructions:
-
-Set the data input directory (the LOGS file) to the 'input_dir' variable.
-
-Set the output directory for the generated PDFs to the 'output_dir' variable.
-
-Set the name of the generated PDF files for the 2- and 3-D plots to the 'twoD_plots_output_pdf_name' and 'threeD_plots_output_pdf_name' variables respectively.
-
-The dictionaries 'global_properties_x_axis' and 'multi_line_plots_x_axis' set the X-axis arguments for the generated 2-D plots. The keys:
-    'plot_variable' Sets the X-axis variable. e.g. star_age or model_number.
-    'x_axis_divider' Allows the units of the X-axis to be manipulated. Options are: None, sec, min, hr, day, yr, kyr, myr, gyr. Example: for 'plot_variable':'star_age' setting 'x_axis_divider':'day' will change the X-axis units to days. Set to None if not in use.
-    'x_axis_scale_type' Allows the scale of the X-axis to be set to linear or log.
-    'x_axis_name_for_plots' Sets the X-axis label.
-    'x_axis_ticklabel_format' Sets the style of the X-axis ticklabels. Can be 'plain' or 'sci' or 'scientific'.
-    'y_axis_ticklabel_format' Sets the style of the X-axis ticklabels. Can be 'plain' or 'sci' or 'scientific'.
-
-The dictionary 'global_properties_plots' takes the Y-axis variables to be plotted as keys and the corresponding Y-axis scale types as the key value. These plots are single line plots.
-
-The dictionary 'multi_line_plots' creates plots with multiple lines for the purpose of comparison. This is a nested dictionary. The keys take the plot titles as their arguments.
-The key values take nested dictionaries as their arguments. The nested dictionaries take the Y-axis variables to be plotted as keys, and the corresponding Y-axis scale types 
-as their keys values. There are no limits on the number of key-value pairs that can be given within the nested dictionaries. Multi-line plots are then created with the nested dicts.
-The same multi-line plot can have both linear- and log-scale variables plotted on the same axes if desired by the user.
-
-The boolean 'only_plot_two_D_graphs' only plots 2-D graphs if set to true, and skips plotting the Kippenhahn graphs.
-
-The dictionary 'Kippenhahn_properties' Takes the arguments for the generated Kippenhahn plots. The keys:
-    'x_axis' Sets the X-axis variable. e.g. star_age or model_number.
-    'y_axis' Sets the Y-axis variable. e.g. star_mass or radius.
-    'overlay_history_line' Allows a line from history.data to be overlayed the heatmap. Set to the variable name in history.data,  e.g. 'mass_conv_core. Set to None if not in use.
-    'overlay_history_line_label' Sets the legend label for the overlayed history line (if used). Set to None if not in use. 
-    'overlay_history_line_colour' Sets the colour of the overlayed history line (if used). Set to None if not in use.
-    'y_axis_min_limit': Sets the minimum Y-axis value to start from. e.g if Y-axis is mass, but you want to plot from mass value 0.9 Msun to the surface, set 'y_axis_min_limit': 0.9 
-    'y_axis_max_limit': Sets the maximum Y-axis value to be plotted. e.g if Y-axis is mass, but you want to plot from the core to mass value 0.8 Msun, set 'y_axis_max_limit': 0.8 
-    'format_x_axis' Formats the X-axis ticks to a certain number of decimal places. e.g. 'format_x_axis':3 allows ticks to have 3 decimal places. Set to None if not in use.
-    'format_y_axis' Formats the Y-axis ticks to a certain number of decimal places. e.g. 'format_y_axis':7 allows ticks to have 7 decimal places. Set to None if not in use.
-    'x_axis_divide_by' Allows the units of the X-axis to be manipulated. Options are: None, sec, min, hr, day, yr, kyr, myr, gyr. Example: for 'plot_variable':'star_age' setting 'x_axis_divider':'day' will change the X-axis units to days. Set to None if not in use.
-    'y_axis_divide_by' Allows the units of the Y-axis to be manipulated. e.g. for 'Y_axis':'radius_cm' setting 'y_axis_divide_by':1e-2 will change the Y-axis units to metres. Set to None if not in use.
-    'z_axis_data_min_cutoff' : If any of the Z-axis data elements are less than 'z_axis_data_min_cutoff', then those Z-axis data elements are set to 'z_axis_data_min_cutoff_replacement'. e.g if 'z_axis_data_min_cutoff':0e0 and 'z_axis_data_min_cutoff_replacement':0e0, then any Z-axis data elements below zero will be set to zero. Set to None if not in use.
-    'z_axis_data_min_cutoff_replacement' : Sets the value a Z-axis element will be replaced with if its value is less than 'z_axis_data_min_cutoff'. Set to None if not in use.
-    'z_axis_data_max_cutoff' If any of the Z-axis data elements are greater than 'z_axis_data_max_cutoff', then those Z-axis data elements are set to 'z_axis_data_max_cutoff_replacement'. e.g if 'z_axis_data_max_cutoff':1e2 and 'z_axis_data_min_cutoff_replacement':1e2, then any Z-axis data elements greater than 100 will be set to 100. Set to None if not in use.
-    'z_axis_data_max_cutoff_replacement' Sets the value a Z-axis element will be replaced with if its value is greater than 'z_axis_data_max_cutoff'. Set to None if not in use.
-    'num_y_axis_elements_for_heatmap' The number of data points the Y-axis will have on the heatmap. A greater number will give more resolution to the heatmap.
-    'x_axis_label_heatmap' The label for the heatmaps x-axis. e.g. 'Star Age [day]'.
-    'y_axis_label_heatmap' The label for the heatmaps Y-axis. e.g. 'Mass [M$_{\\odot}$]'.
-    'x_axis_ticklabel_format' Sets the style of the X-axis ticklabels. Can be 'plain' or 'sci' or 'scientific'.
-    'y_axis_ticklabel_format' Sets the style of the X-axis ticklabels. Can be 'plain' or 'sci' or 'scientific'.
-    'color_bar_scheme_heatmap' Sets the colour scheme of the heatmaps colour bar . For matplotlib colours, go to https://matplotlib.org/stable/tutorials/colors/colormaps.html

-The dictionary 'Kippenhahn_plots' takes the Z-axis variables to be plotted as the key and the Z-axis scale type as the corresponding key value. 
-
-The dictionary comparing_at_unity_plots compares 2 Z-axis variables and plots the result as a 2 level Kippenhahn plot that explicitly shows the result of the comparison above and below unity.
-The keys take the plot titles as their arguments. The key values take lists as their arguments. The list must contain either 1 or 2 variables to be compared against each other and plotted
-to show the result above and below unity. For example if the key 'plot1' has a value ['v', 'csound'], then a Kippenhahn plot of cell_velocity/cell_sound_speed will be created that compares the result above 
-and below unity. Note that the first list value will be divided by the second list value. A key can also take a list with a single element as a value, this is because some MESA outputs are 
-in comparison form already, such as the profile.data output 'v_div_vesc' which is the direct output of cell_velocity/cell_escape_velocity by MESA. This particular example will take the key-value pair form
-of 'plot2': ['v_div_vesc'].
