+/**
+ * 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 <denish@isocra.com>
+ * 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
+ * <tableID>[]=<rowID1>&<tableID>[]=<rowID2> 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
