190	Standard maps should be reference maps	Peter Kovacs	Peter Kovacs	"Should we state in the graph structure concepts that node and arc/edge maps must be reference maps for '''all''' graph types?

It would make writing a general algorithm easier and more convenient since we would have to use `set()` functions instead of `operator[]` only for the ""external"" map types, and all the ""internal"" maps, which are created by the algorithm could be used as reference maps.
Maybe it could also improve the efficiency in some cases, but it is not clear and wasn't tested."	task	closed	critical	LEMON 1.1 release	core	hg main	fixed
