hack makexgmml.py...

...to implement changes requested by MH:

 1. make Erk and Akt nodes of equal size
 2. eliminate outer circle of nodes and edges
 3. make zero-edges light gray
 4. make outlines of nodes with at least one non-zero edge black

The solution of 1 also involved hacking the data files received
from MH to change their second and third lines from

Erk	1	0
Akt	1	0

to

Erk	0.5	0
Akt	0.5	0

Note that all the changes above were made "unconditional".  IOW,
there's no easy way to reverse them other than reverting to the
previous version of makexgmml.py.
