fixing mod order setting, adding in new progress parsing so less error prone, must be used with latest kat version, adding cmd_ags option so that other flags can be passed to kat.run(), like enabling coupling reduction

Adding in map reading/writing class and updates to various gui components, trying to get rotation working but failing so far

Daniel changed Param to AttrParam for alpha in beamSplitter - seems to have broken FINESSE, so I changed it back

Also change SIFlaot to pass through 'None'

This solves the issue that not in all cases the
value of 0 can understood as 'not set'.

adding in fsig command (not parsing yet). See example test_fsig.py in bin folder. Also made component variable an optional argument for xaxis and x2axis which will break previous scripts. Did this as when setting the parameter to tune, the Param object contains whatever component owns that parameter so no need to pass it twice. Also stops someone passing a parameter not for the component stated.

Large amount of changes to the param object which now include being able to put and set parameters and commands. Also adding the modulator component.

adding string conversion for detectors and components to return its name, you can then get outputs like out[kat.pd1] or out['pd1']

Fixed issues with n > 2 gratings and added a pass through test which takes a Finesse script, parses it and then outputs it again (to test input/output of component classes)

changing append to extend for adding base class attribute code. Also adding real and imag properties to the gauss_param object to reflect that it is a complex number

Added abstract class for mirror and beamSplitter classes, providing all of the shared functionality.
