Rake task description and RVM files

Provided a description for the myumbc3:reset rake task so it shows in
the listing. Also added files for RVM specifying ruby 2.0.0-p353 and a
gemset named 'myumbc4'.
The start of group sync, but so much more to do
Importer files now write to tmp... so they're not checked in...
