 *
 * If an options Object is provided, the following attributes are supported:
 *
 *  defaultColor:       Default (initially selected) color.
 *                      Default value: '#FFF'
 *
 *  cellWidth:          Width of each individual color cell.
 *                      Default value: 10
 *
 *  cellHeight:         Height of each individual color cell.
 *                      Default value: 10
 *
 *  cellMargin:         Margin of each individual color cell.
 *                      Default value: 1
 *
 *  boxWidth:           Width of the color display box.
 *                      Default value: 115px
 *
 *  boxHeight:          Height of the color display box.
 *                      Default value: 20px
 *
 *  columns:            Number of columns to display. Color order may look strange if this is altered.
 *                      Default value: 16
 *
 *  insert:             The position to insert the color chooser. 'before' or 'after'.
 *                      Default value: 'after'
 *
 *  colors:             An array of colors to display, if you want to customize the default color set.
 *                      Default value: default color set - see 'defaultColors' below.
 *
 *  displayColorCode:   Display the color code (eg #333333) as text inside the button. true or false.
 *                      Default value: false
 *
 *  colorCodeAlign:     Text alignment used to display the color code inside the button. Only used if
 *                      'displayColorCode' is true. 'left', 'center' or 'right'
 *                      Default value: 'center'
 *
 *  colorCodeColor:     Text color of the color code inside the button. Only used if 'displayColorCode'
 *                      is true.
 *                      Default value: '#FFF' or '#000', decided based on the color selected in the chooser.
 *
 *  onSelect:           Callback function to call after a color has been chosen. The callback
 *                      function will be passed two arguments - the hex code of the selected color,
 *                      and the input element that triggered the chooser.
 *                      Default value: null
 *                      Returns:       hex value
 *
 *  onCellEnter:        Callback function that excecutes when the mouse enters a cell. The callback
 *                      function will be passed two arguments - the hex code of the current color,
 *                      and the input element that triggered the chooser.
 *                      Default value: null
 *                      Returns:       hex value
 *
 *  onClose:            Callback function that executes when the chooser is closed. The callback
 *                      function will be passed one argument - the input element that triggered
 *                      the chooser.
 *                      Default value: null
 *
 *  hideInput           If true, hides the original input when displaying the color picker.
 *                      Default: true
 *
 *  livePreview:        The color display will change to show the color of the hovered color cell.
 *                      The display will revert if no color is selected.
 *                      Default value: false
 *
 *  chooserCSS:         An associative array of CSS properties that will be applied to the pop-up
 *                      color chooser.
 *                      Default value: see options.chooserCSS in the source
 *
 *  displayCSS:         An associative array of CSS properties that will be applied to the color
 *                      display box.
 *                      Default value: see options.displayCSS in the source
 *
 *  inputCSS            An associative array of CSS properties that will be applied to the form input
 *                      ex. {   'float':'left' }
 *
