Support source in multiple files
*Created originally on Bitbucket by [paugier (Pierre Augier)](https://bitbucket.org/%7Beb327c54-cadd-4fce-9edd-f8fe047a9b93%7D/)*
This should work:
```
# util.py
import h5py
const = 1
foo = 1
def func():
return const
def use_h5py():
...
```
Another file:
```
from util import func, foo
from transonic import jit
const = 2
@jit
def main():
print(foo, func(const))
```
Note the possible name clash if everything is written on one Pythran file (and there is no namespace keyword in Python!).
I think Pythran supports source in more that one file, so we could use that.
