/****************************************************************************
This module contains code for the handling of output to files. It is our
strong belief that the usefulness of a program depends greatly on the
quality and flexibility of its output --- unfortunately there is no uniform
measure of quality : a human reader will want a compact and well-formatted
file, whereas a computer will want a file that is easy to parse, and a
computer algebra system will want a file that is in its own format.
At each point in time, the group has a component d_fileoutput, which is
set to the current "style" of output (typically we envision pretty, terse,
gap, tex and latex as desirable styles). This component contains the
virtual function table corresponding to the desired output.
The functions outputting to files are the following :
- printClosure(file,h,p,I) : prints information about one schubert
variety; the list of extremal pairs is contained in h;

Chapter I -- The OutputTraits class.
This class holds all the little details which govern output of data to
files. Although this may seem a lot of detail, it seems that not much less
can be done is one is to automatically produce output suitable for direct
input into programs such as TeX or GAP.
Mostly, constructors are provided for the various output tags :
- OutputTraits(Pretty);
- OutputTraits(Terse);
- OutputTraits(GAP);
