[IGSTK-Developers] igstkVascularNetworkReaderTest Crashing

[Patrick Cheng]

Hi Luis,

Some recent change to the igstkSpatialObject is causing the 
igstkVascularNetworkObjectTest to fail in the Sandbox.

In igstkVascularNetworkRepresentation class, the 'vessel' variable is a 
invalid pointer, because in igstkSpatialObject.h, the return value of
const Self * GetObject(unsigned long id) const
has been changed to NULL.

Please take look at this problem.

Thank you,

Patrick
