updated plot functions

binarycpython/utils/plot_functions.py

 """
-Module that contains plotting routines for single systems.
+Module that contains Functionality to plot different aspect of (binary) systems. 
 
-The idea to do this is to provide the user with some quick
-commands to plot the evolution of a system
+Different routines are defined here to plot orbits, masses, angular momenta etc. 
+
+Its split up into logging string, parsing functions, plotting functions, 
+and one master function called plot_system that will provide ease of use. 
+
+All the loose components here can ofcourse be used in other routines if you want.
 
 There is no preloaded matplotlib rc, you should do that yourself
 
 TODO: This module is not finished yet.
+TODO: Make modules for single system
+TODO: Put all the plotting functions in here
