/**
 * 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

 * @projectDescription Easy element scrolling using jQuery.
 * http://flesler.blogspot.com/2007/10/jqueryscrollto.html
 * @author Ariel Flesler
 * @version 1.4.3.1
 *
 * @id jQuery.scrollTo
 * @id jQuery.fn.scrollTo
 * @param {String, Number, DOMElement, jQuery, Object} target Where to scroll the matched elements.
 *	  The different options for target are:
 *		- A number position (will be applied to all axes).
 *		- A string position ('44', '100px', '+=90', etc ) will be applied to all axes
 *		- A jQuery/DOM element ( logically, child of the element to scroll )
 *		- A string selector, that will be relative to the element to scroll ( 'li:eq(2)', etc )
 *		- A hash { top:x, left:y }, x and y can be any kind of number/string like above.
 *		- A percentage of the container's dimension/s, for example: 50% to go to the middle.
 *		- The string 'max' for go-to-end. 
 * @param {Number, Function} duration The OVERALL length of the animation, this argument can be the settings object instead.
 * @param {Object,Function} settings Optional set of settings or the onAfter callback.
 *	 @option {String} axis Which axis must be scrolled, use 'x', 'y', 'xy' or 'yx'.
 *	 @option {Number, Function} duration The OVERALL length of the animation.
 *	 @option {String} easing The easing method for the animation.
 *	 @option {Boolean} margin If true, the margin of the target element will be deducted from the final position.
 *	 @option {Object, Number} offset Add/deduct from the end position. One number for both axes or { top:x, left:y }.
 *	 @option {Object, Number} over Add/deduct the height/width multiplied by 'over', can be { top:x, left:y } when using both axes.
 *	 @option {Boolean} queue If true, and both axis are given, the 2nd axis will only be animated after the first one ends.
 *	 @option {Function} onAfter Function to be called after the scrolling ends. 
 *	 @option {Function} onAfterFirst If queuing is activated, this function will be called after the first scrolling ends.
 * @return {jQuery} Returns the same jQuery object, for chaining.
 *
 * @desc Scroll to a fixed position
 * @example $('div').scrollTo( 340 );
 *
 * @desc Scroll relatively to the actual position
 * @example $('div').scrollTo( '+=340px', { axis:'y' } );
 *
 * @desc Scroll using a selector (relative to the scrolled element)
 * @example $('div').scrollTo( 'p.paragraph:eq(2)', 500, { easing:'swing', queue:true, axis:'xy' } );
 *
 * @desc Scroll to a DOM element (same for jQuery object)
 * @example var second_child = document.getElementById('container').firstChild.nextSibling;
 *			$('#container').scrollTo( second_child, { duration:500, axis:'x', onAfter:function(){
 *				alert('scrolled!!');																   
 *			}});
 *
 * @desc Scroll on both axes, to different values
 * @example $('div').scrollTo( { top: 300, left:'+=200' }, { axis:'xy', offset:-20 } );
