/** @brief This class is a singleton that handles various parameters
    of the FMD detectors.  
    This class reads from the Conditions DB to get the various
    parameters, which code can then request from here. In that way,
    all code uses the same data, and the interface is consistent.
     
    Some of the parameter managed are 
    - @c fPedestal, @c fPedestalWidth
      Mean and width of the pedestal.  The pedestal is simulated
      by a Guassian, but derived classes my override MakePedestal
      to simulate it differently (or pick it up from a database).
    - @c fVA1MipRange
      The dymamic MIP range of the VA1_ALICE pre-amplifier chip 
    - @c fAltroChannelSize
      The largest number plus one that can be stored in one
      channel in one time step in the ALTRO ADC chip. 
    - @c fSampleRate
      How many times the ALTRO ADC chip samples the VA1_ALICE
      pre-amplifier signal.   The VA1_ALICE chip is read-out at
      10MHz, while it's possible to drive the ALTRO chip at
      25MHz.  That means, that the ALTRO chip can have time to
      sample each VA1_ALICE signal up to 2 times.  Although it's
      not certain this feature will be used in the production,
      we'd like have the option, and so it should be reflected in
      the code.
