Typedefs
using	CeresEngine::EntityActionID = unsigned int
	A numeric type that represents a action.
template<typename T , typename A >
using	CeresEngine::ifEntityAction = typename std::enable_if< isEntityAction< A >, T >::type
	If the type A is a action (as defined by isAction<A>), this type is aliased to T.
template<typename T , typename... As>
using	CeresEngine::ifEntityActions = typename std::enable_if< areEntityActions< As... >, T >::type
	If the types As are all actions (as defined by areActions<As>), this type is aliased to T.

Functions
template<CEntityAction A>
constexpr void	CeresEngine::checkAction ()
	A trait that checks if the type A is a valid action type.

Variables
template<typename A >
constexpr bool	CeresEngine::isEntityAction = std::is_base_of<AbstractEntityAction, A>::value
	A trait that checks if the type C is a action.
template<typename... As>
constexpr bool	CeresEngine::areEntityActions = (isEntityAction<As> && ...)
	A trait that checks if the types As are all actions.
