Added more files from the mr project.
* Changed dir names from '-' to '_'
** Java now likes us to the point where the default test is running.
Datomic stuff
* Schema for places, addresses, and tags.
* Shell script to create postal data in the :post partition.  This file needs to be run in the same directory as a "Canada.csv" file.  Not including that in the repo.
* Added postal-code information as initial data.  "lein datomic initialize" seems to have no trouble loading this.
