Hello,

like to have only one standard function to save graphs, instead of calling
different NetworkX functions, right?
Yes

simply type:
That's what the branch does, too. Only you may not know that those
functions can be found in networkx.

with `make distclean && make`, and it works! Some small suggestions:

I added one check, but it is unpleasant in many ways. First, the (integer)
vertices become strings, and then each edge gets a label encoding a
weight. Well, that's networkx...

to say "the format is the extension", because you do not guess, you simply
use the extension.
How is that not a guess? Anyway, udpated.

(!http://networkx.lanl.gov/reference/readwrite.html), where the different
file formats are detailed.
Done.
