[IGSTK-Developers] tracker heirarchy

[Ziv Yaniv]

Hi all,

After reviewing the Tracker/auroraTracker/polarisTracker classes I 
believe the current hierarchy should be changed. Currently auroraTracker 
and polarisTracker inherit from Tracker, all are complete classes with 
large chunks of exactly the same code in the Aurora and Polaris classes.

I'd like to suggest that Tracker become a virtual base class. Then we 
have NDIAuroraPolarisBase, a virtual base class for the two trackers 
containing all the common functions. Only then do we have the 
AuroraTracker and PolarisTracker which can be instantiated.

                  comments anyone?
                         Ziv
