adding progress bar to parakat.getResults(), better parsig of funcs and changing default fsig name of xbeta/ybeta

adding in new integrator for knm using higher order newton-cotes methods and analytic solution for square aperture

Changing documentation, adding printExtraLines methods to see what commands haven't been parsed into pykat objects. Adding more squeezing to numpy arrays

adding in block selector to loadkatfile and parsecommands, so that it only reads in certain blocks. Fixed factorial code in HG_beam

adding romhom greedypoint file parameter, changing SIfloat to convert numpy arrays, beam_param can accept numpy arrays for computing multiple points

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

wz -> w for gaussian parameters.

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.

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

adding in gauss_param object. Although it doesn't inherit from a complex type it can be used as one in equations as it overrides the various options
