public subroutine sdr_identify_bc_colors(attribute)
Identify all unique boundary colors, after all boundary attributes and
seeds are known.
This has to be done separately from reading the attributes, due to the
interdependence of the boundaries and seed objects. It has to be ensured
that all seed objects are known at this point.
The bc_colors will correspond to the unique color name list, or are 0
if the bc color does not exist in that list.
'none' bc colors are marked negatively as they are to be applied to all
seed colors.
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.
