Write a migration and ActiveRecord model that tracks restaurant reservations. Assume there is a table in your relational database named "reservations".   Reservations have a start time, an end time and a table number. 

Write some ActiveRecord validations that check new reservations for overbooking of the same table in the restaurant. For example, table #10 cannot have 2 reservations  for the same period of time. This validation(s) should check time overlap for both  record creation and updates. 

Unit tests are a must to make sure your double booking validations are working.  (rspec and unittests)
