KataBankOCR-8-9-2013 setup

Initial setup for KataBankOCR project

* Created folders for src and docs
* Added user story and features documents to docs folder
* Added empty solution to src
* Added code and test projects to solution
* Added references to nunit and source project to the test project

That should be everything the initial setup needs. Since this is my
first time doing TDD, I may be wrong about that, but it matches up with
what I read and the Nunit test runner isn't complaining.
