cocoex module has no __version__

[brockho]

Contrary to the cocopp and cocoprep modules, the cocoex module does not have an accessible __version__ attribute. In order to check which version is installed, the presence of such an attribute will be much more convenient than trying to uninstall the module via pip uninstall cocoex and then looking at the print out (which is what I can do right now). Low priority issue though.

For cocopp it is done like:

import pkg_resources
__version__ = pkg_resources.require('cocopp')[0].version
del pkg_resources

in the module __init__.py file.
