/**
* Allows you to resort elements within a container by dragging and dropping. Requires
* the Draggables and Droppables plugins. The container and each item inside the container
* must have an ID. Sortables are especially useful for lists.
*
* @see Plugins/Interface/Draggable
* @see Plugins/Interface/Droppable
* @author Stefan Petre
* @name Sortable
* @cat Plugins/Interface
* @param Hash options A hash of options
* @option String accept The class name for items inside the container (mandatory)
* @option String activeclass The class for the container when one of its items has started to move
* @option String hoverclass The class for the container when an acceptable item is inside it
* @option String helperclass The helper is used to point to the place where the item will be
* moved. This is the class for the helper.
* @option Float opacity Opacity (between 0 and 1) of the item while being dragged
* @option Boolean ghosting When true, the sortable is ghosted when dragged
* @option String tolerance Either 'pointer', 'intersect', or 'fit'. See Droppable for more details
* @option Boolean fit When true, sortable must be inside the container in order to drop
* @option Integer fx Duration for the effect applied to the sortable
* @option Function onchange Callback that gets called when the sortable list changed. It takes
* an array of serialized elements
* @option Boolean floats True if the sorted elements are floated
* @option String containment Use 'parent' to constrain the drag to the container
* @option String axis Use 'horizontally' or 'vertically' to constrain dragging to an axis
* @option String handle The jQuery selector that indicates the draggable handle
* @option DOMElement handle The node that indicates the draggable handle
* @option Function onHover Callback that is called when an acceptable item is dragged over the
* container. Gets the hovering DOMElement as a parameter
* @option Function onOut Callback that is called when an acceptable item leaves the container.
* Gets the leaving DOMElement as a parameter
* @option Object cursorAt The mouse cursor will be moved to the offset on the dragged item
* indicated by the object, which takes "top", "bottom", "left", and
* "right" keys
* @option Function onStart Callback function triggered when the dragging starts
* @option Function onStop Callback function triggered when the dragging stops
* @example $('ul').Sortable(
* {
* accept : 'sortableitem',
* activeclass : 'sortableactive',
* hoverclass : 'sortablehover',
* helperclass : 'sorthelper',
* opacity: 0.5,
* fit : false
* }
* )
