proposing new module structure

[d3netxer]

• for consistency just use lowercase and underscores for library names.
• change name of GOSTnet.py to core.py
• change init.py from:

from GOSTnets.GOSTnet import *

to

from .core import *
from .calculate_od import *
from .optimization import *
etc...

I am working on the Sphinx documentation now and the autodoc functionality. It is spitting out function names like "GOSTnets.GOSTnet.find_graph_avg_speed"; so this way should make the function names look nicer too.

yes, I think for modules we can go with short, all-lowercase names, and they can contain underscores.

so I did this. One thing this does is want the extra underlying libraries to have their dependencies too. So we may want to continue thinking about this.

Also, once this looks good, let's try to update the version on PiPy
