DESCRIPTION

The  class  contains  parts  of FDM that are specific for lattice
grids.

CONSTRUCTORS AND INITIALIZATION

See the base class FDM.

MEMBER FUNCTIONS

Only the constructor should be called explicitly by the user, the
rest  of the functions are utility functions used by FDM for lat­
tice grids. See the base class FDM.
