class AliPHOSv1: public AliPHOSv0

Def ctor.

 We store 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).

 dtor

 Add a hit to the hit list.
 A PHOS hit is the sum of all hits in a single crystal from one primary and within some time gate

 called at the end of each track (primary) by AliRun
 hits are reset for each new track
 accumulate the total hit-multiplicity

 called at the end of each event by AliRun
 accumulate the hit-multiplicity and total energy per block
 if the values have been updated check it

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

 Digitize one CPV hit:
 On input take exact 4-momentum p and position zxhit of the hit,
 find the pad response around this hit and
 put the amplitudes in the pads into array digits

 Calculate the amplitude in one CPV pad using the
 cumulative pad response function

 Cumulative pad response function
 It includes several terms from the CF decomposition in electrostatics
 Note: this cumulative function is wrong since omits some terms
       but the cell amplitude obtained with it is correct because
       these omitting terms cancel
