Visiting a variant-or-single event

Description

Equivalent of std::visit for tcspc::variant_or_single_event.

This overload set of functions together take any tcspc::variant_or_single_event as the second parameter.

(Currently there are only overloads for a single event argument, with no variadic version.)

Functions
template<typename Visitor, typename EventList>
constexpr auto	tcspc::visit_variant_or_single_event (Visitor &&visitor, variant_event< EventList > &&event)
	Apply a visitor to a tcspc::variant_event (rvalue).
template<typename Visitor, typename EventList>
constexpr auto	tcspc::visit_variant_or_single_event (Visitor &&visitor, variant_event< EventList > &event)
	Apply a visitor to a tcspc::variant_event (lvalue).
template<typename Visitor, typename EventList>
constexpr auto	tcspc::visit_variant_or_single_event (Visitor &&visitor, variant_event< EventList > const &event)
	Apply a visitor to a tcspc::variant_event (const lvalue).
template<typename Visitor, typename Event>
constexpr auto	tcspc::visit_variant_or_single_event (Visitor visitor, Event &&event)
	Apply a visitor to an event that is not a tcspc::variant_event.
