   * barMenus {Boolean}, default true, Turns bar menus on/off
   *
   * freezableCells {Boolean}, default true, Turns ability to freeze cells on/off
   *
   * allowToggleState {Boolean}, default true, allows the spreadsheet to be toggled from write/read

   *
   * error {Function} default function(e) { return e.error; }, is triggered on errors from the formula engine
   *
   * encode {Function} default is a special characters handler for strings only, is a 1 way encoding of the html if entered manually by the editor.  If you want to use html with a function, return an object rather than a string
   *

   * contextmenuLeft {Object} default is standard list of commands for context menus when right click
   *	  Javascript example:
   *		  {
	 *			  'What I want my command to say': function() {}
	 *		  }
   *
   * contextmenuCell {Object} default is standard list of commands for context menus when right click or click on menu dropdown
   *	  Javascript example:
   *		  {
	 *			  'What I want my command to say': function() {}
	 *		  }
   *
   * alert {Function} default function(msg) {alert(msg);}
   * prompt {Function} default function(msg, callback, initialValue) {callback(prompt(msg, initialValue));}
   * confirm {Function} default
   *	  function(msg, callbackIfTrue, callbackIfFalse) {
	 *		  if (confirm(msg)) {

    expected:    (string describing the set of expected tokens)
    recoverable: (boolean: TRUE when the parser has a error recovery rule available for this particular error)
