Detailed Description

This class provides a repository for common regex patterns so that we don't keep recompiling them over and over again. Some convenience methods are provided to make the interface more similar to the convenience functions on String. The convenience methods on String are deprecated except for one-shot patterns (which, by definition, are not in loops).
