I've fixed the _boxed formatting to strip ANSI codes when calculating string lengths (so you can use ANSI colours properly)

changed the colours for the "failed systems" warning so it's absolutely obvious

wrapped the JSON ensemble output in a write_ensemble() function which automatically gzips or bzips depending on the filename extension (or this can be explictly set in grid_options['compress_ensemble'] ).

shows:
current grid status (#/# and modulo)
estimate of time remaining and time to finish
memory use (of all processes)
time per run

add methods to grid.py:

rename_grid_variable
update_grid_variable
clean

add functions to functions.py:

convfloat
datalinedict
pad_output_distribution

Fixed some complaints that pylint had and fixed a correct mass ratio lower bound in the interpolators

Working on the M&S grid now: added alot of verbose output, and making sure all the interpolators are freed. Now I need to add the eccentricity as options and output for plots. Also reformatted
