/**
   <P>A trivial class used to hold internal objects for CRLineAnalyzer.  See <A HREF="~JD~crla~EJD~">CRLineAnalyzer</A>.</P>

   <P><CODE><I><B>Source code:</B> &nbsp;<A HREF="../../../CODE/xbn/config/CRLAObjects.java">CRLAObjects.java</A></I></CODE></P>

   <P>The purpose of this class is to prevent internal objects from being created and destroyed rapid-fire.  The CRLineAnalyzer class itself <I>is</I> created and destroyed rapid-fire--once for each line in the source text.  So instead of creating and destroying the objects needed internally in it, they are created and persistently exist in this class.  This object as a whole is then passed (rapid fire) into CRLineAnalyzer.</P>
