\file  sort.c
\brief This file contains GKlib's various sorting routines

These routines are implemented using the GKSORT macro that is defined
in gk_qsort.h and is based on GNU's GLIBC qsort() implementation.

Additional sorting routines can be created using the same way that
these routines where defined.
