This is the first release with a manual. In the process, some
member functions of grid classes have been renamed to be more consistent
with other OE toolkits.
Added new functions to add, subtract, multiply or divide one grid
by another grid. OEAddGrid, OESubtractGrid, OEMultiplyGrid, OEDivideGrid.
Grids can now be attached to molecules or other grids and written
to OEB files and read back in. It is important to use the new function
OEInitGridHandlers to set up a stream for writing or reading these
attached grids. Also, grids attached to molecules will automatically be
loaded in Vida 3.
Added new overload of OEIsReadableGrid and OEIsWriteableGrid that
take a filename string.
Fixed a bug where writing Delphi grids when the grid was larger than
(65,65,65) resulted in a spacing of 1.0 Angstrom regardless of the actual
spacing of the grid.
