-  Styles to make ordinary <INPUT type="text"/> look like a spinbutton/spinbox control.
-  Use with jQuery.SpinButton.js to provide the spin functionality by reacting to mouse etc.
-  (Requires a reference to the JQuery library found at http://code.jquery.com/)
-  (Hats-off to John Resig for creating the excellent JQuery library. It is fab.)
-
-  This control is achieved with no extra html markup whatsoever and uses unobtrusive javascript.
-
-  Written by George Adamson, Software Unity (george.jquery@softwareunity.com) September 2006.
-  Big improvements added by Mark Gibson, (mgibson@designlinks.net) September 2006.
-
-  Do contact me with comments and suggestions but please don't ask for support.
-  As much as I'd love to help with specific problems I have plenty to get on with already!
-
-  Go ahead and use it in your own projects. This code is provided 'as is'.
-  Sure I've tested in heaps of ways. Its good for me, but you use it at your own risk.
-  SoftwareUnity and I are certainly not responsible if your computer sets fire to the sofa,
-  hacks into the pentagon, hijacks a plane or gives you any kind of hassle whatsoever.
-
-  If you'd like your spin-button image in a different place then you'll need to alter both
-  the CSS below and the javascript isMouseOverUpDn() function to accommodate the new position.
-  You could even have left and right buttons either side of the textbox.

-/**
- * SpinButton control.
- *
- * Adds bells and whistles to any ordinary textbox to
- * make it look and feel like a SpinButton Control.
- *
- * Supplies {@link external:jQuery.fn.SpinButton}).
- *
- * Originally written by George Adamson, Software Unity (george.jquery@softwareunity.com) August 2006:
- * - Added min/max options.
- * - Added step size option.
- * - Added bigStep (page up/down) option.
- *
- * Modifications made by Mark Gibson, (mgibson@designlinks.net) September 2006:
- * - Converted to jQuery plugin.
- * - Allow limited or unlimited min/max values.
- * - Allow custom class names, and add class to input element.
- * - Removed global vars.
- * - Reset (to original or through config) when invalid value entered.
- * - Repeat whilst holding mouse button down (with initial pause, like keyboard repeat).
- * - Support mouse wheel in Firefox.
- * - Fix double click in IE.
- * - Refactored some code and renamed some vars.
- *
- * Modifications by Jeff Schiller, June 2009:
- * - provide callback function for when the value changes based on the following
- *   {@link https://www.mail-archive.com/jquery-en@googlegroups.com/msg36070.html}.
- *
- * Modifications by Jeff Schiller, July 2009:
- * - improve styling for widget in Opera.
- * - consistent key-repeat handling cross-browser.
- *
- * Modifications by Alexis Deveria, October 2009:
- * - provide "stepfunc" callback option to allow custom function to run when changing a value.
- * - Made adjustValue(0) only run on certain keyup events, not all.
- *
- * Tested in IE6, Opera9, Firefox 1.5.
