Adds two fake pole points (90S and 90N) to the leftmost dimension of the given data.

A 2-dimensional array with latitude as the leftmost dimension.
The results are returned in an array of the same type as Data, and with dimensions ny+2 x nx where ny x nx are the dimensions of Data.
This function adds two fake pole points (i.e. 90S and 90N) to data where there are no pole points to get nice round -90 (90S) and 90 (90N) points. It's assumed that the "y" (leftmost dimension) coordinate is latitude. Missing values are assigned to the data for these added points.
