BUG: Fixing the template running stage.

Running template building for each subject was not working.

This is the first patch to attempt to resolve found issues.
STYLE: Remove python warning and reorganize imports

The imports to a module are usually at the top of the file.  Only when
the function is bundled up as a nipype node do the imports need to be
redundantly embedded in the function module itself so that they are self
sufficient in the cluster environment.
STYLE: Removed master_config dictionary in favor of descriptive dictionary names

ENH:  Added commandline printing option
ENH: Fixed command line for singleSession and template
STYLE: Moved imports in template to top of file
BUG: Fixed DataGrabber for template workflow
