// Class defining methods for shooting Flat or Bit random numbers, double or
// integers.
// It provides methods to fill with double flat values arrays of
// specified size, as well as methods for shooting sequences of 0,1 (bits).
// Default boundaries ]0.1[ for operator()().
// This is derived from RandFlat and is a drop-in replacement. However
// the shootBit() and fireBit() methods are stateless (which makes them
// an order of magnitude slower, but allows save/restore engine status
// to work correctly).
