"""Martel based parser to read NBRF formatted files.

This is a huge regular regular expression for NBRF, built using
the 'regular expressiona on steroids' capabilities of Martel.


Just so I remember -- the new end of line syntax is:
  New regexp syntax - \R
     \R    means "\n|\r\n?"
     [\R]  means "[\n\r]"

This helps us have endlines be consistent across platforms.

    The Record class is meant to make data easy to get to when you are
    just interested in looking at NBRF data.
