/// Base class for functors to get a nice hierarchy diagram /** Base class for functors to get a nice hierarchy diagram
class eoFunctorBase
That's actually quite an understatement as it does quite a bit more than
just that. By having all functors derive from the same base class, we can
do some memory management that would otherwise be very hard.
The memory management base class is called eoFunctorStore, and it supports
a member add() to add a pointer to a functor. When the functorStore is
destroyed, it will delete all those pointers. So beware: do not delete
the functorStore before you are done with anything that might have been allocated.
