-The problem with this approach is that `type` is a string (and by default it is 255 characters). This is a little ridiculous. For comparison, if we had a state machine with X states, would we describe the states with strings `"State1", "State2", etc` or would we just enumerate the state column and make it an integer? This gem will allow us to use an integer for the `type` column.

-Note: The mapping here can start from whatever integer you wish, but I would advise not using 0. The reason being that if you had a new class, for instance `PriorityFirm`,  but forgot to include set the mapping, it would effectively get `to_i` called on it and stored in the database. `"Priority".to_i == 0`, so if your mapping included 0, this would create a weird bug.

 If you want to convert a polymorphic association that is already a string, you'll need to set up a migration. (Assuming SQL for the time being, but this should be pretty straightforward.)
