Detailed Description

template<typename EnumType>
class EnumIterator< EnumType >

bidirectional iterator over an enum type

It can be instantiated using any enum (or C++11 strongly-typed enum) value; the most common expected use scenario has iterators emitted by EnumRange and WholeEnum via standard begin() and end() calls.

In order for the iterator to work, it is mandatory that the underlying enum type's representation values be sequential.

The iterator does not check for bounds when incrementing or decrementing, that responsibility is left to the caller.
