Probe GUI

Invoked by jrc probe myprobe.prb command. You can zoom and pan using the mouse wheel. The first numbers (Site#) indicate the site numbers used in JRCLUST (sorted in bottom-to-top, left-to-right order), and the second numbers (Chan#) indicate the channel # stored in a recording file. Sites from the same shank are grouped by the same color.
