<h2>stat_r.c -- statistical operations</h2>
<blockquote>
<p>Qhull records many statistics. These functions and
macros make it inexpensive to add a statistic.
<p>As with Qhull's global variables, the statistics data structure is
accessed by a macro, 'qhstat'. If qh_QHpointer is defined, the macro
is 'qh_qhstat->', otherwise the macro is 'qh_qhstat.'.
Statistics
may be turned off in user_r.h. If so, all but the 'zz'
statistics are ignored.</p>
