Move shell scripts from out of package.json into Gruntfile with grunt-shell, and update the README to reflect that change.  In src/index.html, reference the debug version of the grid library which resides in dist/
Refactor tests: break out leetTh test functionality into its own file, and change the leetGrid test to check for the correct number of columns and rows.  Also create a mockDataCreator service that can be shared between the test files - this service can be used to create an arbitrary leetGrid configuration object.
