/** @addtogroup Utilities
One of the invalidator operators. Use this one as a 'hat' on an operator
that is defined to work on a generic datatype. This functor will then check
the return type of the operator and invalidate the fitness of the individual.
This functor is used in algorithms that work with straight eoMonOp, eoBinOp
or eoQuadOp operators, for instance eoSGA. Note that eoGenOp derived operators
generally do invalidate the fitness of the objects they have changed.
Return value means "Has_Changed" and not "Needs_To_Be_Invalidated"
as successive invalidation are not really a problem
