DEV: STAPLE Gramatically correct
COMP: Fixed transform type to be a list as is required.
COMP: Fix logic bug and added DS for STAPLE.
ENH: Move back to using an SVN repository for holding data.

The Use of a tarball was too combersome and expensive for maintaining
a complete atlas.  This reverts to a single SVN repository so
that small changes can be easily made and tracked.
ENH: Fix regular expressions for Reference Atlas.

The CMakeLists.txt file needed more precise regular expressions
to avoid .avn directories.
