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
