[IGSTK-Developers] Setting the Polaris Spectra illuminator rate?

[Patrick Cheng]

Hi Janne Beate,

To add onto my previous email. It makes more sense to have subclasses of 
NDICommandInterpreter such as:
   PolarisCommandInterpreter
   AuroraCommandInterpreter
This class will warp those tracker specific commands.

This is consistent with the IGSTK tracker classes hierarchy. We can 
switch to use PolarisCommandInterpreter in the PolarisTracker class.

You can play with that if you have time and we can discuss the 
possibility of include this refactoring into the next release.

Thank you,

Patrick
