/*
* jQuery miniColors: A small color selector
*
* Copyright 2011 Cory LaViska for A Beautiful Site, LLC. (http://abeautifulsite.net/)
*
* Dual licensed under the MIT or GPL Version 2 licenses
*
*
* Usage:
*
* 1. Link to jQuery: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
*
* 2. Link to miniColors: <script type="text/javascript" src="jquery.miniColors.js"></script>
*
* 3. Include miniColors stylesheet: <link type="text/css" rel="stylesheet" href="jquery.miniColors.css" />
*
* 4. Apply $([selector]).miniColors() to one or more INPUT elements
*
*
* Options:
*
* disabled [true|false]
* readonly [true|false]
*
*
* Specify options on creation:
*
* $([selector]).miniColors({
*
* optionName: value,
* optionName: value,
* ...
*
* });
*
*
* Methods:
*
* Call a method using: $([selector]).miniColors('methodName', [value]);
*
* disabled [true|false]
* readonly [true|false]
* value [hex value]
* destroy
*
*
* Events:
*
* Attach events on creation:
*
* $([selector]).miniColors({
*
* change: function(hex, rgb) { ... }
*
* });
*
* change(hex, rgb) called when the color value changes; 'this' will refer to the original input element;
* hex is the string hex value of the selected color; rgb is an object with the RGB values
*
*
* Change log:
*
* - v0.1 (2011-02-24) - Initial release
*
*
* Attribution:
*
* - The color picker icon is based on an icon from the amazing Fugue icon set:
* http://p.yusukekamiyamane.com/
*
* - The gradient image, the hue image, and the math functions are courtesy of
* the eyecon.co jQuery color picker: http://www.eyecon.ro/colorpicker/
