syre src

- 2D structural analysis (with Matlab PDE Toolbox)
- peak short-circuit current evaluation (HWC condition, see ECCE2021 paper)
- added radial geometrical scaling to main GUI
- added the possibility to load a custom geometry from the FEMM file (after dxf import in FEMM)
- improved the possibility to easily select the number of quadrants for flux maps evaluation
- Motor-CAD interface improved
- added the export to Ansys-Maxwell (still work-in-progress)

MMM GUI updates:
- transient short-circuit computation (see ECCE2021 paper)
- updated the field names in motorModel structure
- added the possibility to change the dq-axis convention (from SyR to PM motor and vice versa)
- added end-winding length (to avoid AC Joule loss model overestimation)

Other updates:
- new PM-SyRM model (THOR), with MMM data (see ECCE2021, WEMDCD2021 or ECCE2019 papers)
- added the MMM data to mot_01 and RAWP motors
- updated the user manual (merge between main GUI and MMM) and updated reference list

Some bug fixed
