JobSchedule e networkdays namespace

[cadu-leite]

For a better namespace or "dot path"...
I believe would be a good idea
take both classes of the networkdays file
and put each one in his own file ...
networkdays

├── networkdays
│   ├── __init__.py
│   ├── networkdays.py

to be ...

├── networkdays
│   ├── __init__.py
│   ├── networkdays.py
│   └── jobschedule.py

and expose both on init.py , to have one less level on namespaces.
