Defines bound classes for real numbers.
Scalar type:  Basic class is eoRealBounds, a pure virtual.
The following pure virtual methods are to be used in mutations:
So mutation can choose
There is also a uniform() method that generates a uniform value (if possible, i.e. if bounded) in the interval.
Derived class are eoRealInterval that holds a minimum and maximum value, eoRealNoBounds the "unbounded bounds" (infinity, +infinity) eoRealBelowBound the halfbounded interval [min, +infinity) eoRealAboveBound the halfbounded interval (infinity, max]
THis file also contains the declaration of *the* global object that is the unbounded bound
