/**
* TableDnD plug-in for JQuery, allows you to drag and drop table rows
* You can set up various options to control how the system will work
* Copyright © Denis Howlett
* Licensed like jQuery, see http://docs.jquery.com/License.
*
* Configuration options:
*
* onDragStyle
* This is the style that is assigned to the row during drag. There are limitations to the styles that can be
* associated with a row (such as you can't assign a border—well you can, but it won't be
* displayed). (So instead consider using onDragClass.) The CSS style to apply is specified as
* a map (as used in the jQuery css(...) function).
* onDropStyle
* This is the style that is assigned to the row when it is dropped. As for onDragStyle, there are limitations
* to what you can do. Also this replaces the original style, so again consider using onDragClass which
* is simply added and then removed on drop.
* onDragClass
* This class is added for the duration of the drag and then removed when the row is dropped. It is more
* flexible than using onDragStyle since it can be inherited by the row cells and other content. The default
* is class is tDnD_whileDrag. So to use the default, simply customise this CSS class in your
* stylesheet.
* onDrop
* Pass a function that will be called when the row is dropped. The function takes 2 parameters: the table
* and the row that was dropped. You can work out the new order of the rows by using
* table.rows.
* onDragStart
* Pass a function that will be called when the user starts dragging. The function takes 2 parameters: the
* table and the row which the user has started to drag.
* onAllowDrop
* Pass a function that will be called as a row is over another row. If the function returns true, allow
* dropping on that row, otherwise not. The function takes 2 parameters: the dragged row and the row under
* the cursor. It returns a boolean: true allows the drop, false doesn't allow it.
* scrollAmount
* This is the number of pixels to scroll if the user moves the mouse cursor to the top or bottom of the
* window. The page should automatically scroll up or down as appropriate (tested in IE6, IE7, Safari, FF2,
* FF3 beta)
*
* Other ways to control behaviour:
*
* Add class="nodrop" to any rows for which you don't want to allow dropping, and class="nodrag" to any rows
* that you don't want to be draggable.
*
* Inside the onDrop method you can also call $.tableDnD.serialize() this returns a string of the form
* []=&[]= so that you can send this back to the server. The table must have
* an ID as must all the rows.
*
* Known problems:
* - Auto-scoll has some problems with IE7 (it scrolls even when it shouldn't), work-around: set scrollAmount to 0
*
* Version 0.2: 2008-02-20 First public version
* Version 0.3: 2008-02-07 Added onDragStart option
* Made the scroll amount configurable (default is 5 as before)
* Version 0.4: 2008-03-15 Changed the noDrag/noDrop attributes to nodrag/nodrop classes
* Added onAllowDrop to control dropping
* Fixed a bug which meant that you couldn't set the scroll amount in both directions
* Added serialise method
