linesman 0.3.2 dependency to networkx

[papachoco]

Hi,

Is there any way we can relax the constraint to networkx=1.7 for linesman? We are using the latest version of networkx (1.11)

Thanks

Carlos

According to several other bug reports (#30, #37), 1.11 seems to have some issues. Are you not running into these same issues? There seemed to be quite a few people impacted.

I wonder if we still see these issues w/ network 2.1

The networkx API has changed some in 2.x, I've taken a stab at updating linesman's usage in #43
