Detailed Description

Interface class that Binds all the transform classes together for usage with Qt constructs such as Images and Tables.

This transform wrapper runs transforms (FFT etc.) in threads.

Todo:

Multi-threading: Cannot handle multi-threading. Enforce "wait" until transform is complete.
