+ * Angular JS Multi Select
+ * Creates a dropdown-like button with checkboxes. Accepts an array of object & modifies it based on the checkboxes status.
+ *
+ * Usage:
+ *
+ *      <div
+ *          multi-select 
+ *          list-items="data" 
+ *          item-label="firstName lastName" 
+ *          item-ticker="selected"  
+ *          orientation="vertical" 
+ *          max-labels="4"
+ *          max-height="500"
+ *          is-disabled="false" >
+ *      </div>
+ *   
+ *   or
+ *
+ *      <multi-select 
+ *          ...
+ *          ...
+ *      </multi-select> 
+ *          (*** be careful with browser compatibility)
+ *
+ * Attributes: 
+ *
+ *      list-items (REQUIRED):
+ *          $scope variable. Array of objects such as
+ *          [
+ *              { firstName: "John", lastName: "Robert"     , ....., selected: false },
+ *              { firstName: "Jane", lastName: "Angel"      , ....., selected: true },
+ *              { firstName: "Luke", lastName: "Skywalker"  , ....., selected: true },
+ *              { firstName: "John", lastName: "Wayne"      , ....., selected: true }
+ *          ]    
+ *      item-label (String) (REQUIRED) 
+ *          The object property that you want to display on the button & checkboxes. Separate multiple values by space. 
+ *          Example: item-label="firstName lastName"          
+ *      item-ticker (String) (REQUIRED):
+ *          Column name with a boolean value that represent the state of a checkbox. For example, in the list-items sample above, 
+ *          the item-ticker is "selected". So if selected === true, checkbox will be ticked. If selected === false, checkbox will not be ticked.
+ *          If not specified, the default will be "selected"
+ *      orientation (String - "vertical" | "horizontal")
+ *          Orientation of the list of checkboxes. 
+ *          If not specified, the default will be "vertical".
+ *      max-labels (String)
+ *          Maximum number of items that will be displayed in the dropdown button. If not specified, will display all selected items. 
+ *          Example: "2" -> Using the list-items above, then button will display the first two selected: "Jane Angel, Luke Skywalker, ..."
+ *      max-height (String)
+ *          Maximum height of the list of checkboxes in pixels. Will show scrollbar on overflow.
+ *          Example: "100". 
+ *      is-disabled (String - "true" | "false") 
+ *          Disable or enable the checkboxes. 
+ *          If not specified, the default will be "false".
