Data provider for testAddWithBadDataProvider().

Since AddClass::add() can throw exceptions, it's time to give it some data that will cause these exceptions.

add() should throw exceptions if either of it's arguments are not numeric, and we will generate some test data to prove that this is what it actually does.
