----------------------------+-----------------------------------------------
We should have an option to g.laplacian() to return the signless
Laplacian, which is attracting attention these days, and which is
calculated by {{{D+A}}} instead of {{{D-A}}} (see p. 12 of
http://www.doiserbia.nb.rs/ft.aspx?id=0350-13020795011C, for example).
Thanks to Steve Butler for the feature request.
