Write a method that "scrambles" a string of lower-case letters, 'origText' using a key, 'key'. The key will contain every lower-case letter from "a" to "z" exactly once, but in any order. The key is used to convert the 'origText' into a coded message by replacing every letter in 'origText' by the letter immediately following that letter in 'key'. Look at the test data for specific examples.
