Library case Y602: Expanding and contracting grids for PARAB=T.

In this example, attention is focussed wholly on how to use PLANT for expanding and/or contracting the Y-extent of the grid.

It is useful in parabolic calculations when PARAB=T. The grids created this way can also be used for independent purposes.

The example is made for Y-direction grid specification. The PLANT statements headed by SCXS?? should perform an exactly corresponding functions for the X-direction domain width, XULAST, to that performed here for YVLAST, provided the pointer AZXU is set to GRND.
