check tests if they were modified. This topic cleans itk tests and
reduces developer frustration when committing changes to test.

BUG: Do not create static initialized ITK objects

Allocating an ITK object with a factory new method during static
initialization, caused the ITK factories to be registered. Which
triggers other libraries to be loaded. This can not occur during
static initialization.

Thread safe lazy initialization is required for these cases.
