Pop up a dialog window for input of a number.

        Arguments: title is the title of the dialog window,
        prompt is a text mostly describing what numerical information to input.
        default: default value
        minval: minimum value for input
        maxval: maximum value for input

        The number input must be in the range minval .. maxval if these are
        given. If not, a hint is issued and the dialog remains open for
        correction. Return the number input.
        If the dialog is canceled,  return None.

        Example (for a TurtleScreen instance named screen):
        >>> screen.numinput("Poker", "Your stakes:", 1000, minval=10, maxval=10000)
