Port over API classes from the MATLAB code to Python

[DrPaulSharp]

We need to port over the following classes from the MATLAB version of RAT to python:

• Add the controlsClass #7 -- Added in added the controlsClass #10
• eventManager -- Added in Adds code to build ratMain extension #21
• backgroundsClass -- Added in Add Models and Project for RAT API #6
• baseContrasts -- Added in Add Models and Project for RAT API #6
• contrastsClass -- Added in Add Models and Project for RAT API #6
• customFileClass -- Added in Add Models and Project for RAT API #6
• dataClass -- Added in Add Models and Project for RAT API #6
• domainContrastsClass -- Added in Add Models and Project for RAT API #6
• domainsClass -- Added in Add code to handle calculation options #14
• layersClass -- Added in Add Models and Project for RAT API #6
• multiTypeTable -- Not required
• parametersClass -- Added in Add Models and Project for RAT API #6
• projectClass -- Added in Add Models and Project for RAT API #6
• resolutionsClass -- Added in Add Models and Project for RAT API #6
• tableUtilities -- Not required, broad equivalent is the ClassList added in Adds "ClassList" for use as table-like collection of objects #4

We also need the following utility functions:

• duplicateName -- Added in ClassList in Adds "ClassList" for use as table-like collection of objects #4
• indexOutOfRange -- Covered by python builtins
• invalidNumberOfInputs -- Not required
• invalidOption -- Covered by pydantic Add Models and Project for RAT API #6
• invalidProperty -- Covered by Add code to handle calculation options #14
• invalidType -- Covered by pydantic Add Models and Project for RAT API #6
• invalidValue -- Covered by pydantic Add Models and Project for RAT API #6 & added the controlsClass #10
• nameNotRecognised -- Covered by ClassList Adds "ClassList" for use as table-like collection of objects #4
• unrecognisedR1Problem -- not necessary, use regular python error types
• projectClasstoR1 -- added in Adds conversion between R1 .mat files and Python Projects #55
• r1toProjectClass -- added in Adds conversion between R1 .mat files and Python Projects #55
• bayesShadedPlot -- added in Adds Bayesian plots to Python #52
• cornerPlot -- added in Adds Bayesian plots to Python #52
• histp -- added in Adds Bayesian plots to Python #52
• mcmcplot -- added in Adds Bayesian plots to Python #52
• plotBayes -- added in Adds Bayesian plots to Python #52
• plotBayesCorrFig -- removed from matlab RAT
• plotRefSLD -- Added in added plotting feature using matplotlib  #24
• plotRefSLDHelper -- Added in added plotting feature using matplotlib  #24
• shade -- not required as already in matplotlib
• copyProperties -- Not required
• customEnum -- Not required
• isText -- Not required
• mockFunction -- Not required
• validateNumber -- Covered by pydantic Add Models and Project for RAT API #6
• validateOption -- Covered by pydantic Add Models and Project for RAT API #6

We will need to port over all the examples -- most done in #36
