The fractions are processed recusrively from inside out.  The `tail'
is the one to discover the inner most part of a continued fraction
(i.e., the bottom rows).  Higher levels add to the nucleous built
already under them.

In Stage 1 the members of the continued fractions are marked as
such. In the second stage they being are procesed.


The minimum conditions here are three un-interrupted levels of
fractions.
