Class Description

 CalRecon

 CalRecon is the over-all manager for Fast MC calorimetry.  It must
 be instantiated for each detector (or change to smearing parameters)
 but need only be cleared between events belonging to the same
 detector

 Constructor.   Primary job is to assemble various parameters
 describing detector geometry and resolution.

 Get rid of allocated memory, obsolete pointers.

 Process an event.  For each MC particle, check to see whether it's
 "smearable".  If so, propagate, then smear energy and transverse
 position.

 Output standard cluster quantities to ascii file.

 Check a) that we have a final-state particle b) particle type.
 Must be electron/positron, photon, or an acceptable hadron.
 c) energy.  Must be non-negligible.

 Somehow get access to needed detector parameters.  For now, use the
 name to identify a set of parameters.  Could also use it to identify
 a file, or to just ask (from some parameter server class) for information
 about the "ambient" detector, if any.

 Result of this call is to initialize the following fields in CalRecon:
       nBarrel   pBarrels
       nEndcap   pEndcaps
 so that at the end have a list of pointers to barrels, arranged in
 order of increasing R, and a list of endcap in order of increasing z

 Swim particle with initial conditions described in pTraj through
 the detector.  Return true if particle showers in the detector
 (where the coil counts as part of the detector)
