 This modification of the contour3d_demo example uses extend3d=True to
 extend the curves vertically into 'ribbons'.

 contourf differs from contour in that it creates filled contours, ie.
 a discrete number of colours are used to shade the domain.

 This example demonstrates mplot3d's offset text display.
 As one rotates the 3D figure, the offsets should remain oriented the
 same way as the axis label, and should also be located "away"
