NOTES
----------------------------------------------------
* When using other libraries that may have built in "Event" namespace,
i.e. Typescript, you can use "eventjs" instead of "Event" for all example calls.

----------------------------------------------------

----------------------------------------------------

target.removeEventListener(type, listener, useCapture);
// Attempts to perform as fast as possible.
Event.add(type, listener, configure);
Event.remove(type, listener, configure);
* You can turn prototyping on/off for individual features.
----------------------------------------------------
Event.modifyEventListener = true; // add custom *EventListener commands to HTMLElements.
Event.modifySelectors = true; // add bulk *EventListener commands on NodeLists from querySelectorAll and others.
* Example of setting up a single listener with a custom configuration.
