Takes at least some of the sting out of regexes

I love regular expressions; when applied correctly, they can greatly simplify your code as you search for/parse/replace text. They can be a real pain, though, as they become more complex. Patterns make getting your regexes correct a lot easier. The interactive highlighting makes debugging your regexes simpler--you can back up and go forward to see where youve gone awry. Great tool. Would love to see support for capture groups.
