Inherits TimeVaryingTransform

Base class for Transforms that have a single child transform


WrapperTransforms are the base class for plugins that have a child transform. It inherits from TimeVaryingTransform so that it can properly handle a child transform that is also time varying, WrapperTransform itself has no requirement to be time varying. The main purpose of WrapperTransform is to intelligently implement simplify and smartCopy, all other calls are just passed to the child.
