/**
* Display a nice easy to use multiselect list
* @Version: 2.0.2
* @Author: Patrick Springstubbe
* @Contact: @JediNobleclem
* @Website: springstubbe.us
* @Source: https://github.com/nobleclem/jQuery-MultiSelect
* @Notes: If select list is hidden on page load use the jquery.actual plugin
* to resolve issues with preselected items placeholder text
* https://github.com/dreamerslab/jquery.actual
*
* Usage:
* $('select[multiple]').multiselect();
* $('select[multiple]').multiselect({ placeholder: 'Select options' });
* $('select[multiple]').multiselect('reload');
* $('select[multiple]').multiselect( 'loadOption', [{
* name : 'Option Name 1',
* value : 'option-value-1',
* checked: false
* },{
* name : 'Option Name 2',
* value : 'option-value-2',
* checked: false
* }]);
