This script is actually not needed since we've already got a helper function that does this.  See CreateDatabase in this script.

The CreateDatabase function is one we should put in under the ./dev/services/.. folder though since it is a re-usable function. I'll add this function to the ./dev/services... folder for the change-set I'm currently working on.
