diff plugin/transform/Transformer.cpp @ 328:21bd032ae791

* Introduce new Transform class which contains data necessary to describe the
  context for a plugin -- the plugin's name and output, the step/block size
  etc (formerly spread across ExecutionContext and TransformFactory).  Other
  code hasn't been updated to use this yet.
* Rename existing Transform stuff to Transformers (because they run Transforms)

I'm still not 100% sure about this change, don't rely on it.
