-/**
- * TextAreaExpander plugin for jQuery
- * v1.0
- * Expands or contracts a textarea height depending on the
- * quatity of content entered by the user in the box.
- *
- * By Craig Buckler, Optimalworks.net
- *
- * As featured on SitePoint.com:
- * http://www.sitepoint.com/blogs/2009/07/29/build-auto-expanding-textarea-1/
- *
- * Please use as you wish at your own risk.
- */
-
-/**
- * Usage:
- *
- * From JavaScript, use:
- * $(<node>).TextAreaExpander(<minHeight>, <maxHeight>);
- * where:
- * <node> is the DOM node selector, e.g. "textarea"
- * <minHeight> is the minimum textarea height in pixels (optional)
- * <maxHeight> is the maximum textarea height in pixels (optional)
- *
- * Alternatively, in you HTML:
- * Assign a class of "expand" to any <textarea> tag.
- * e.g. <textarea name="textarea1" rows="3" cols="40" class="expand"></textarea>
- *
- * Or assign a class of "expandMIN-MAX" to set the <textarea> minimum and maximum height.
- * e.g. <textarea name="textarea1" rows="3" cols="40" class="expand50-200"></textarea>
- * The textarea will use an appropriate height between 50 and 200 pixels.

-/**
- * 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
