Currently, the java GIS routines for handling ascii grid files uses a
PersistentVector class that was originally created for Morpho when raster are
too large for RAM. This method works but is really quite slow.
A good part of this slowness is probably due to the treatment of the raster data
as Java objects (actually as string arrays).
It is likely that a new approach using Java NIO buffers could greatly speed up
these virtual memory routines. This should be investigated at some point in the
future.
