* eve.on
[ method ]
**
* Binds given event handler with a given name. You can use wildcards “`*`” for the names:
| eve.on("*.under.*", f);
| eve("mouse.under.floor"); // triggers f
* Use @eve to trigger the listener.
**
> Arguments
**
- name (string) name of the event, dot (`.`) or slash (`/`) separated, with optional wildcards
- f (function) event handler function
**
= (function) returned function accept one number parameter that represents z-index of the handler. It is optional feature and only used when you need to ensure that some subset of handlers will be invoked in a given order, despite of the order of assignment.
> Example:
| eve.on("mouse", eat)(2);
| eve.on("mouse", scream);
| eve.on("mouse", catch)(1);
* This will ensure that `catch` function will be called before `eat`.
* If you want to put you hadler before not indexed handlers specify negative value.
* Note: I assume most of the time you don’t need to worry about z-index, but it’s nice to have this feature “just in case”.
