+### Register Transforms
+### This is interesting because we don't expect all transforms to be
+### available on all platforms. To do this we allow things to fail at
+### two levels
+### 1) Imports
+### If the import fails the module is removed from the list and
+### will not be processed/registered
+### 2) Registration
+### A second phase happens when the loaded modules register method
+### is called and this produces an instance that will used to
+### implement the transform, if register needs to fail for now it
+### should raise an ImportError as well (dumb, I know)
