Incompatible with networkx 2.0

[Langmans]

I'm not really proficient in python but I managed to get the part that handles installing eggs through pip to force install networkx 1.11. It's better to upgrade the code to networkx 2.0 I think, but this should do in the mean time right?

In eggs/__init__.py:

for dep in ["decorator", "lxml", "PyYAML", "six", "jinja2", "psutil", "patch", "pydot"]:
    destpath = "{0}/{1}".format(path, dep)
    if not os.path.exists(destpath):
        pip.main(["install", "--target={0}".format(destpath), dep])
    sys.path.append(destpath)

destpath = "{0}/networkx".format(path)
if not os.path.exists(destpath):
    pip.main(["install", "--target={0}".format(destpath), "networkx==1.11"])
sys.path.append(destpath)
