Asynchronously append data to a file, creating the file if it does not yet exist.

@param {(string|Buffer|integer)} path - file path or file descriptor
@param {(string|Buffer)} data - data to append
@param {(Object|string)} [options] - options
@param {Function} clbk - callback to invoke after appending data to the file

@example
function onAppend( err ) {
    if ( err ) {
        console.log( err.message );
    }
}

appendFile( './beep/boop.txt', 'appended something\n', onAppend );
