python -m codecov fails

[jayvdb]

python -m codecov
C:\Python27\python.exe: No module named codecov.__main__; 'codecov' is a package and cannot be directly executed
Command exited with code 1

Adding a file called codecov/__main__.py would fix this right?

[jayvdb]

Yup.

Without it, on Appveyor I need to fiddle with the PATH

If this was fixed, I could use simply python -m codecov.

Also note that the codecov.exe created by setuptools has been very flaky on Windows (see CleanCut/green#127), so being able to avoid the setuptools created codecov.exe can be helpful as an alternative.
