1.1.1

• Bug fixes / optimizations from previous version
• You can now fire an element's appear event by calling element.appear()
• Optional settings as a second parameter - element.appear(fn, options)
• one: whether to fire the appear event every time the element becomes visible, or just the first time (default: true)
• data: arbitrary data to be passed as arguments to the function when the event is fired

1.1

• Listens for dom and style changes in addition to binding to the window scroll
• Fires appear only when element is (a) in the viewable window and (b) element.is(':visible') == true.

1.0

Very basic implementation. Only binds to the window's scroll event.
