eventMouseover
==============
Triggered when the user mouses over an event.
function( *event*, *jsEvent*, *view* ) { }
`event` is an [Event Object](../event_data/Event_Object) that holds the event's information (date, title, etc).
`jsEvent` holds the native JavaScript event with low-level information such as mouse coordinates.
`view` holds the current [View Object](../views/View_Object).
Within the callback function, `this` is set to the event's `` element.
