ISIN = ISINPOLY(X,Y,XP,YP) Finds whether points with coordinates X and Y are inside or outside of a polygon with vertices XP, YP. Returns matrix ISIN of the same size as X and Y with 0 for points outside a polygon, 1 for inside points and 0.5 for points belonging to a polygon XP, YP itself.

- diff DIFF - This function tries to differentiate the variables in
- end END - basic end method for HFRC objects.
- length LENGTH - returns number of times in HFRC object.
- size SIZE - returns [ (num times), (num gridpts) ].
