- arg scheduler that works at click level (but disable it). works but not ideal experience.
- do not provide automatically imported api functions and objects in `imaginairy` root module
- horrible hack to overcome horrible design choices by easy_install/setuptools
The hack modifies the installed script to remove the __import__ pkg_resources line
If we don't do this then the scripts will be slow to start up because of
pkg_resources.require() which is called by setuptools to ensure the
"correct" version of the package is installed.
before modification example:
```
__requires__ = 'imaginAIry==14.0.0b5'
__import__('pkg_resources').require('imaginAIry==14.0.0b5')
__file__ = '/home/user/projects/imaginairy/imaginairy/bin/aimg'
with open(__file__) as f:
exec(compile(f.read(), __file__, 'exec'))
```
