Adding a couple test cases

There are other tests that can be based off these files, it's simple.
Added some more test cases

These probably won't work out of the box, would need minor adjustments
to file paths.
Updates to how actual dates are retrieved and aesthetic changes

Function GetContractActualDates was not properly picking up the start
and end date if a student had two contracts in a completed state.  This
should be fixed now.  Also shrunk the debug text size to 75% on the
print.css page so it all fits on single page when printed.
Create README.md
Moved twilio-assignment-bee to its own repo
