Challenge 16 - Tap code translation
Tap code is a way to communicate messages via a series of taps (or knocks) for each letter in the message. Letters are arranged in a 5x5 polybius square, with the letter "K" being moved to the space with "C". Each letter is translated by tapping out the row and column number that the letter appears in, leaving a short pause in-between. If we use "." for each tap, and a single space to denote the pause, and another space is added between the groups of taps for each letter to give the final code. 1 2 3 4 5

Write a function that returns the tap code if given a word, or returns the translated word (in lower case) if given the tap code. When translating from tap-code, default to the letter "c" if the tap-code ". ..." is found.
