private function TRBDF23D_curv(f, A, B, C, D, E, dt, x)
SOLVE A 3D SEQUENCE OF 1D DIFFUSION PROBLEMS.
GHOST CELLS ARE ACCOMODATED AS THEY PROVIDE
A CONVENIENT MEMORY SPACE FOR BOUNDARY CONDITIONS.
Note that this function also plays the role of abstracting
away the grid structure so that the individual 1D lines are
solved using arrays for differences instead of structure members
Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed
arrows point from an interface to procedures which implement that interface.
This could include the module procedures in a generic interface or the
implementation in a submodule of an interface in a parent module.
