Modifed DetectorPaddle to make use of the new transformXYZ functions.
Implemented PCAL in CLASECDetector (untested).  Created class CLASECGeometryProperties to contain static final geometry parameters that describe the EC detectors' geometry (only PCAL so far).  Created class CLASECModule to construct EC modules and allow entire EC modules to be translated and rotated as a single unit rather than many individual strips.
