ContextEvent

An event fired by a context requester to signal it desires a named context. A provider should inspect the context property of the event to determine if it has a value that can satisfy the request, calling the callback with the requested value if so. If the requested context event contains a truthy multiple value, then a provider can call the callback multiple times if the value is changed, if this is the case the provider should pass a dispose method to the callback which requesters can invoke to indicate they no longer wish to receive these updates.
