adding in more ROMHOM computation and weighting file generations as well as some knm computations utilities. Adding more functions in beam parameter object for plotting parameters

adding lambda default wavelength property, also fixing q factor computations that need to link to this value

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

Conflicts:
	pykat/finesse.py

tracing doesn't require anymore than maxtem 0 so use that for tracing and then return to previous value.

udpdating setup files and requirements. Fixing and simplifying the output select from a kat_run object. Internally it always stores output data as a 2d array, even if noxaxis is used. This simplifies the selection of output data greatly

So far this is not yet fit for general use though.
