More matching algorithms! CFAlgoWireOverlap: finds the range of wires on a plane containing the hits on that plane. Then with the 3 wire-ranges (one per plane) finds the area in Z-Y space of the overalp of all 3 ranges. The larger the area, the better the match. CFAlgoVolumeOverlap works the same way but also takes into account overlap in Time-Space. Parameter calculated is Area of overlap in Z-Y space times overlap in Time (X) space computed in cm^3 --David Caratelli
