/*
 * Functions for packing and unpacking (unsigned) integers into file
 *
 * Parameters:
 * a[]        array of unsigned integers
 * bits       how many (low) bits are used
 * nelems     number of integers to save
 * maxnelems  maximum number of integers to read
 * f          file handle
 *
 * Note: f must be opened before call and will be left open,
 * caller must close it.
 * This allows, i.e.,  packing several arrays even with different bit counts
 * in one file.
