KataDictionaryReplacer

This kata is about making a simple string replacer. It is inspired by Corey Haines Lightning talk about practicing. (aac2009.confreaks.com/06-feb-2009-20-30-lightning-talk-under-your-fingers-corey-haines.html)

Create a method that takes a string and a dictionary, and replaces every key in the dictionary pre and suffixed with a dollar sign, with the corresponding value from the Dictionary.
