// Description: CCalDetector will provide the basic functionallity of a 
//              detector factory. It has a construct method that describes 
//              the construction sequence of the detector. It has a Name, 
//              a file associated with it, and a collection of other 
//              CCalDetectors that are supposed to be inside this one.
