Simple event emitter class.
Supports "omni-listeners" through its
omniEventstatic property. An omni-listener is added/removed as any other listener but it will be triggered with ANY event rather than with a specific one.Events can be strings or symbols. Internally, uses Map and Set instances to deal with events and listeners so in theory anything that can be used as a Map key can be used as an event, only strings and symbols are guaranteed to work however.
