Example usage

//all settings are optional and default to the shown values
gp.config({ zoom_level:0				//panorama zoom level, default 0
		, tiles_prefix:'image_'			//tile image prefix, useful for montage
		, path_to_image:'panos'			//panorama will create this folder and store the panorama in it
		, output_prefix:'output_'		//prefix for the panorama image
		, tmp_dir_prefix: 'gpan_tmp'	//temp folder prefix
		, pub: true						// path_to_image relative to app root or public folder
		})

//each setting can be changed separately
gp.config('zoom_level', 3);

//each setting value can be returned
var zoom = gp.config('zoom_level') // returns 3

//retrieve panorama image for Times Square, New York
gp.savePanorama('3q57BxQpP8dNzwD0R5PIzg', function(err,path){
	if(err)
		return handleError(err);
	console.log(path); //will return the full path to the panorama image
});
