Add sample predicated openers/closers

This adds a sample predicated opener/closer pair based off of regular
expressions.

The opener accepts a regular expression and will provide all of its
numbered captured groups.

The closer accepts a format string and uses the parameters (capture
groups) as the format parameters.
