Utility class to handle flags.
This class can be used to handle flags of a same enumeration type.
It is meant to be used as an argument for functions and member methods and as part of events.
Flags<E>
objects can be easily or-ed and and-ed with other instances of the same type or with instances of the type E
(that is, the actual flag type), thus converted to the underlying type when needed.
