[IGSTK-Developers] Memoryleak in igstk

[Matt Turek]

Torleif,

Nice catch, there is indeed a memory leak. It is related to the 
CoordinateReferenceSystemDelegator and its use of another object (for 
instance a SpatialObject) for event invocation. This results in a 
circular smart pointer reference as the SpatialObject owns a 
CoordinateReferenceSystemDelegator.

I'll be working on a fix as we move forward with the consolidation this 
week.
