'google' namespace package needs a boilerplate '__init__.py' for Python2 compatibility

[Tres Seaver]

Otherwise, installing alongside another package using the google namespace can break (right now, protobuf).  The boilerplate can be just a one-liner:

__import__('pkg_resources').declare_namespace(__name__)

If you are trying to support a non-setuptools installation (Why?), then you need a bulkier version:

try:
    import pkg_resources
    pkg_resources.declare_namespace(__name__)
except ImportError:
    import pkgutil
    __path__ = pkgutil.extend_path(__path__, __name__)
