  /***
   * A plugin to add Context Menu (mouse right+click), it subscribes to the cell "onContextMenu" event.
   * The "contextMenu" is defined in the Grid Options object
   * You can use it to change a data property (only 1) through a list of Options AND/OR through a list of Commands.
   * A good example of a Command would be an Export to CSV, that can be run from anywhere in the grid by doing a mouse right+click
   *
   * Note:
   *   There is only 1 list of Options, so typically that would be use for 1 column
   *   if you plan to use different Options for different columns, then the CellMenu plugin might be better suited.
   *
   * USAGE:
   *
   * Add the slick.contextmenu.(js|css) files and register it with the grid.
   *
   * To specify a menu in a column header, extend the column definition like so:
   * var contextMenuPlugin = new Slick.Plugins.ContextMenu(columns, grid, options);
   *
   * Available grid options, by defining a contextMenu object:
   *
   *  var options = {
   *    enableCellNavigation: true,
   *    contextMenu: {
   *      optionTitle: 'Change Priority',
   *      optionShownOverColumnIds: ["priority"],
   *      optionItems: [
   *        { option: 0, title: 'none', cssClass: 'italic' },
   *        { divider: true },
   *        "divider" // just the string is also accepted
   *        { option: 1, iconCssClass: 'fa fa-fire grey', title: 'Low' },
   *        { option: 3, iconCssClass: 'fa fa-fire red', title: 'High' },
   *        { option: 2, iconCssClass: 'fa fa-fire orange', title: 'Medium' },
   *        { option: 4, iconCssClass: 'fa fa-fire', title: 'Extreme', disabled: true },
   *      ],
   *      commandTitle: 'Commands',
   *      commandShownOverColumnIds: ["title", "complete", "start", "finish", "effortDriven"],
   *      commandItems: [
   *        { command: 'export-excel', title: 'Export to CSV', iconCssClass: 'fa fa-file-excel-o', cssClass: '' },
   *        { command: 'delete-row', title: 'Delete Row', cssClass: 'bold', textCssClass: 'red' },
   *        { command: 'help', title: 'Help', iconCssClass: 'fa fa-question-circle',},
   *        { divider: true },
   *      ],
   *    }
   *  };
   *

   *    maxHeight:                  Maximum height that the drop menu will have, can be a number (250) or text ("none")
   *    width:                      Width that the drop menu will have, can be a number (250) or text (defaults to "auto")
