Add a method to match recursively paths against Regexp

Hi devs,

For some needs I had in my application, I created this feature, in order to simplify my application's code. It may be interesting for some users.

About the code, I believe it is still refactorable, so if you consider I have to make any modification on it, please let me know and I will immediately adapt it to make it consistent with the rest of the repository's codebase.

Cheers,
Carlos.
