Simulations of Exoplanet Polarised Lightcurves
Testing Git functions correctly.
Added archils-universe.h & archils-universe.c utilities files and linked them into programme.
Currently nothing useful yet in these files.
Modified main.c - removed the printf statement
Added VERY BASIC reading from a config file.
Currently only stored in local variables.
Plan to add commenting and structure support in next iteration.
Added comment support (via '!')
Tidied up main loop.
Added structure for exoplanet data to be stored in.
Added data checking measures, both programme and user end.
Commented the majority of code.
Moved the parser into a new input.c file.
Created a new main.c file and linked in input.c.
Moved structure define from input.c into global.h.
Removed unused header file.
'exo' body now defined in main.c.
Added default parameter value support if values not found in config.txt
exo struct now initialised to default values.
Defined default values in global.h.
Added studbook.h to input.c and now booleans are used to determine if parameters have been read from file.
Removed some magic numbers from input.c and instead used defines at the top of the file.
Changed input.h to modules.h, as this header file will link to all modules not just the input one.
Removed nPhot from Body structure and is now used as a separate global variable (it didn't make sense to keep it as a property of the body).
Created and linked in photonLoop.c where the main simulation will occur.
Added files to hold functions written by individual authors before they are committed into main code.
Added output.c and linked in for future use.
Example function written to freddys_func.c
Included more header files in eshs_func.c
Added arc-utils.c and arc-utils.h for utility functions.
Added arcRand to arc-utils.c.
Added comments to help me understand

Added some comments and corrected spelling of 'tau', otherwise I'll end
up calling it 'tau' rather than 'tao' and confuse the program as well as
myself.
Included an isotropic scattering function in eshs_func.c

I'm not sure if what I've done is correct - I've had no experience
taking structures from different files or calling to functions in
different files. So if I've done something wrong, don't hesitate to add
suggestions on how to fix it.
moved everything from eshs_func.c into esh.c

So you can delete the file 'eshs_func.c' because everything I need is in
'esh.c'
