Thanks to Andrew's diligent efforts to track down and fix a couple of
unrelated issues in Base, I'm pleased to announce that LightGraphs master
now supports GML via Andrew's ParserCombinator package.
You'll have much better performance on a recent (0.4.0-dev+6325 or later)
build, but graphs load in both 0.3 and 0.4.
