Thomas Dehaeze 7575aee987 Add metrology element (change of base, computation of error)
Lot's of new things:
- try to use less .mat files
- computation of setpoint and error in the cartesian frame fixed to the granite
- change of base to have the errors w.r.t. the NASS base
- add script to plot setpoint, position and error
