//Open file selector 
/**
 * File Explorer powered by ArOZ Online File System
 * To pop up a file selector and return an object of files, you can call the following function with the given variable.
 * For example, this is a function which FFmpeg Factory calls to the file selector
 * 
 * ao_module_openFileSelector("FFFSelector","addFileFromSelector",undefined,undefined,true);
 * This will allow the file selector get files (as selectMode default value is "file") and allow multiple selections
 * The selectMode option provide modes for file / folder / mix, where mix means user can select both files and folders
 * The allowMultiple means if the user can select multiple files. True for allow and false for disallow multi selections.
 *
 * To catch the callback of the selector, you can put the following script into your callBack function (In this case, 'addFileFromSelector')
 * 
 * function addFileFromSelector(fileData){
 *  result = JSON.parse(fileData);
 *   for (var i=0; i < result.length; i++){
 *    var filename = result[i].filename;
 *    var filepath = result[i].filepath;
 *    //DO SOMETHING HERE
 *   }
 *  }
 * 
 * REMINDER
 * If you call this function in default mode, please use the "ao_module_openFileSelectorTab" and pass in the relative location of AOR (Root of ArOZ) as the first variable.
 * You will also need to handle the listen of chnage in the uid in localStorage for cross tab communication
