### Default Settings ###
eg.: You can override default control like this:
$.fn.rating.options.cancel = 'Clear';
*/
$.fn.rating.options = { //$.extend($.fn.rating, { options: {
cancel: 'Cancel Rating', // advisory title for the 'cancel' link
cancelValue: '', // value to submit when user click the 'cancel' link
noCancel: false, // option to not show the cancel button
split: 0, // split the star into how many parts?
// Width of star image in case the plugin can't work it out. This can happen if
// the jQuery.dimensions plugin is not available OR the image is hidden at installation
starWidth: 16//,
//NB.: These don't need to be pre-defined (can be undefined/null) so let's save some code!
//half: false, // just a shortcut to control.split = 2
//required: false, // disables the 'cancel' button so user can only select one of the specified values
//readOnly: false, // disable rating plugin interaction/ values cannot be changed
//focus: function(){}, // executed when stars are focused
//blur: function(){}, // executed when stars are focused
//callback: function(){}, // executed when a star is clicked
}; //} });
/*--------------------------------------------------------*/
/*
### Default implementation ###
The plugin will attach itself to file inputs
with the class 'multi' when the page loads
