Added the truncate and the hasNoBoundAtAll methods in eoRealBounds.

Browse source 
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
