// Description:
//     Base class for all simple, geometric trajectories (i.e. trajs that 
//     don't describe tracks).  Inherits from Trajectory.  Supports 
//     (via accept() function) Visitor pattern for adding functionality.
//
// Environment:
//      Software developed for the BaBar Detector at the SLAC B-Factory.
