Appends the necessary amount of spaces to the string until it has the givn
length. No Exception is thrown, if the length of the String is shorter than
the given length, but nothing will happen and a message will be printed to
the System.out.


@param s
the String to expand.
@param length
the desired length of the String to be returned.
@return A String that represents the content of the old String including
extra whitespaces.
