Incorrect usage of e.directed

pygraphml/pygraphml/graphml_parser.py

Line 67 in 8c719ed

if e.directed() != graph.directed:

Hello,
The directed attribute of e is not a function it is a boolean attribute.
Here is the error I am getting:
File "/users/trunkle/anaconda2/lib/python2.7/site-packages/pygraphml/graphml_parser.py", line 67, in write
if e.directed() != graph.directed:
TypeError: 'bool' object is not callable

Suggest removing the parens () from directed on two lines, line 67 and line 68.
Works for me.
Thanks,
Tim.
