Provides the semantics for a nested list of tri-state checkboxes, using the HTML5
"indeterminate" property. When attached to a jQuery element jquery-qubit
listens for change events to input[type=checkbox] elements, and updates
the checked and indeterminate based on the checked values of any checkboxes
in child elements of the DOM.
This plugin is used by jQuery Bonsai. For a full usage example please see there.
$('ul#the-list').qubit();
