Teem-gprobe - Shows off the functionality of the gage library

**SYNOPSIS**

teem-gprobe-i<nin>-k<kind>[-v<verbosity>]-q<query>\fR

**DESCRIPTION**

./teem-gprobe: Shows off the functionality of the gage library. Uses gageProbe() to query various kinds of volumes to learn various measured or derived quantities.
