// This function returns a string that has the specified capitalization performed.
// cap_type specifies what type of capitalization to use.  Valid values are:
//
//   U - Uppercase
//   L - Lowercase
//   P - Proper case (first letter upper, the rest lower)
//   N - No change to capitalization (default if none specified)
//
// EXAMPLES:
//
//    enforce_capitalization("Test String", "U")
// returns:
//    TEST STRING
//
//    enforce_capitalization("Test String", "P")
// returns:
//    Test string
//
