The former simply set values to the boundary values in case they are out
The latter allows to short-cut all bound-checks when no need
SOme day I will put this in utils, and have a eoRealBounds.cpp in the
pre-compiled library
but in generic format.
They are used at the omoment only in eoEsStdevXOver.h that calls a crossover
on the object variables, then a crossover on teh stdev vectors!
A piece of cake :-)
