Regular Expression Validator

I have been needing a simple regular expression validator and am unhappy with the few that I found, so I have created my own. You can get it here: http://lukepaynesoftware.com/projects/regular-expression-validator/

Please note that I don’t plan to make this any bigger than what it is, I know there is so much more it could do. But just for the simple task to validating a regular expression and testing a string against it, this works fine.
