output now correctly returns detector values when using out['name']. If yaxis is used to specify multiple outputs values per detector the result of out[name] is a 2d array

adding in new photodiode object which has f1,phi1,f2,phi2,etc., properties so that they can be tuned/put/set. Not fully transffered over from previous one yet.

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']

2d plotting examples, probably want to wrap these plots up in a function to make it easier in future. Fixed ordering of output rows/cols in the stored matrix for 2d outputs.

in readable form.

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

mirror params.

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

objects that have properties dynamically added to themselves need to declare themselves as new classes, with a base class of the original. Otherwise when we add properties we add them to all instances.

- extending SIfloat to work with lists
- adding SIfloat to axis conversion.
