Exported 'production' SUS models into the SVN for use in python

Original (and more detailed) post: SWG:12283

I have added two scripts and a folder to the Common/MatlabTools of the Sus SVN. The folder is called ExportedModels and it contains exported [A,B,C,D] matrices for making state-space models for 13 suspension types (HLTS_model, QUAD_model, HAUX_model, etc.). It also contains a SUS_projections struct that contains a summary of the OSEM to euler bais changes for most suspensions, also organized by suspension type.

Instructions to navigate the structs can be found in export_SUS_production_models.m, and export_SUS_projection_matrices.m; both inside Common/MatlabTools/

The idea is that these two can be imported into other programming languages (I'm thinking python right now) for analysis, scripting or any other things that people might want.

The use I have in mind right now is for OSEM calibration using ISI drives, following the work we're doing with Oli [see LHO:84296]. But could be handy for something else.
