Examine recon histograms

Most of the RECON histograms are the same ones used for the RTH online monitoring system, and undergo the same statistical comparison to the 'expected' distributions. Histograms that fail this comparison are flagged for the monitor's further investigation. (Not implemented yet).

Plot ID=DCHD should show a flattish shape in the barrel with maybe a 20-30% rise to the endcaps.

Plot ID=DTFD should show a flat phi.

Plot ID=TZND should show a sharp spike near zero.

D should show a smooth efficiency for putting hits on tracks vs CDC layer number. A dip in layers 0 and 1 are expected.
