+/**
+ * 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 (c) 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
+ * dragHandle
+ *     This is the name of a class that you assign to one or more cells in each row that is draggable. If you
+ *     specify this class, then you are responsible for setting cursor: move in the CSS and only these cells
+ *     will have the drag behaviour. If you do not specify a dragHandle, then you get the old behaviour where
+ *     the whole row is draggable.
+ * 
+ * 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.
+ *
+ * Other methods:
+ *
+ * $("...").tableDnDUpdate() 
+ * Will update all the matching tables, that is it will reapply the mousedown method to the rows (or handle cells).
+ * This is useful if you have updated the table rows using Ajax and you want to make the table draggable again.
+ * The table maintains the original configuration (so you don't have to specify it again).
+ *
+ * $("...").tableDnDSerialize()
+ * Will serialize and return the serialized string as above, but for each of the matching tables--so it can be
+ * called from anywhere and isn't dependent on the currentTable being set up correctly before calling
+ *
+ * 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 serialize method
+ * Version 0.5: 2008-05-16 Changed so that if you specify a dragHandle class it doesn't make the whole row
+ *                         draggable
+ *                         Improved the serialize method to use a default (and settable) regular expression.
+ *                         Added tableDnDupate() and tableDnDSerialize() to be called when you are outside the table
