If itk_common does the initial clone then you get the right branch.

This is tricky to implement.  The commands to switch to the proper
branch depend on the starting state of the local repository.  Does
the branch already exist locally?  Does it already track the upstream
branch?  What if we are on another branch and there are local
modifications (git will refuse to switch branches)?

If users just start with a clean directory (no source tree) and
follow the script's instructions then everything is setup right.
The way to reset to the script's defaults is "rm -rf ITK".

What if the local tracking branch has not been set up?
