Class Description

 Implementation version v0 of PHOS Manager class
 Layout EMC + PPSD has name GPS2

*-- Author: Yves Schutz (SUBATECH)

 ctor

 ctor : title is used to identify the layout
        GPS2 = 5 modules (EMC + PPSD)
 We use 2 arrays of hits :

   - fHits (the "normal" one), which retains the hits associated with
     the current primary particle being tracked
     (this array is reset after each primary has been tracked).

   - fTmpHits, which retains all the hits of the current event. It
     is used for the digitization part.

 dtor

 Add a hit to the hit list.
 A PHOS hit is the sum of all hits in a single crystal
   or in a single PPSD gas cell

 Applies the energy calibration

 Makes the digits from the sum of summed hit in a single crystal or PPSD gas cell
 Adds to the energy the electronic noise
 Keeps digits with energy above fDigitThreshold

 Just prints an information message

 Create new branche in the current Root Tree in the digit Tree

 1. Reinitializes the existing RecPoint, TrackSegment, and RecParticles Lists and
 2. Creates a branch in TreeR for each list
 3. Steers the reconstruction processes
 4. Saves the 3 lists in TreeR
 5. Write the Tree to File

 Accumulates hits as long as the track stays in a single crystal or PPSD gas Cell
