Copied RotateSliceEulerRefFrame from develop branch to UCSB plugin
Wrote template versions of itk<>dream3d conversion functions (this seems nicer than the current solution of a different function for each variable type)
-This is the first time I've ever done anything with templates so I may have done something wrong (tested with DiscreteGuassianBlur with no issues)
-I'm not sure if templates are going to be more confusing for people who are writing filters (maybe it would be better to just overload?)
