Addressed issues for CGM2

This issue was addressed in CGM2 4.2:

• When you create normalized moments and powers using MATLAB or Python, the generated units for the model outputs are Nmm/Kg and Watts/kg. After you save the C3D in Nexus and reopen the trial, the units no longer change to Nmm and Watts, as long as your labels fulfill any of the following criteria:
  
  • They match the usual Plug-in Gait normalized model output names
  • They match the usual Plug-in Gait normalized model output names followed by an underscore and by 0..N characters ( _suffix )
  • They contain the text Normalized or Normalised.
