# A graphBPH is a graphNEL with certain additional constraints

# The nodes of a graphBPH are divided into two sets:
# normal nodes and "edge nodes"

# The 'edgeNodePattern' is a regular expression that is
# used to define the two node sets (based on the node names)

# The intention is that a graphBPH may not be modified once
# it has been created
