|bool||operator() (EOT &_eo1, EOT &_eo2)|
|eoQuadOp< EOT > &||op|
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
