+/** @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.
