Update the neighbor stencil positions for the Boundaries
Before, positions in the original treeIDs were assigned to
the boundary element lists. Update these now with level-wise positions in
the tem_levelDesc_type "total list".
When no element is found, the value in nghElems is 0. This has to be
treated in this routine. If an empty neighbor relation is encountered, the
last valid neighbor is used for all other neighbors
Assertion:
Before this routine, we should have:
scheme%globBC( iBnd )%nElems( iLevel )
scheme%globBC( iBnd )%elemLvl( iLevel )%elem%val( iElem ))
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.
