 * Description: part of STAR HBT Framework: AliFemtoMaker package
 *  PicoEvents are last-step ultra-compressed "events" just containing
 *  bare information about the particles of interest.  They have already
 *  gone through Event and Track cuts, so only Pair cuts are left.
 *  PicoEvents are *internal* to the code, and are stored in the
 *  Event-mixing buffers.
 *
