The invoker is a mechanism which allows for external invocation of handlers
based on indexes passed as arguments through the shift left operator
This allows a dispatcher to be invoked like a stream which takes in indexes
using the same facility for output streams.
An invoker can be instantiated and while being instantiated bound to an instance of an existing dispatcher and a function which acts as an Aggregator.
