It provides a new dict attribute process_env and a setter method called set_envvar.
The latter accepts two arguments: name and value
The name does not need to be passed in uppercase, and will automatically be prefixed with WHEN_CHANGED_ to prevent conflicts.
eg. self.set_envvar('myvar', 'myvalue') will result in an environment variable WHEN_CHANGED_MYVAR = myvalue.
