Instead of requiring iteration to be able to list new jobs and existing jobs so that they can be claimed, allow for attaching callbacks to the jobboard where instead of requiring iteration those callbacks will be automatically called by the jobboard internally when events are recieved. Breaking change: renames transition notifier to notifier since it is really not just a notifier for transitions but is a generic notifier of events occuring (and details about those events). This is an internal api so its not expected that this will cause any issues (it's not expected for external users to be creating instances of this class).

Testing and requirements
Requirements
Because TaskFlow has many optional (pluggable) parts like persistence backends and engines, we decided to split our requirements into two parts:
- things that are absolutely required by TaskFlow (you can't use
TaskFlow without them) are put to
requirements.txt; - things that are required by some optional part of TaskFlow (you
can use TaskFlow without them) are put to
optional-requirements.txt; if you want to use the feature in question, you should add that requirements to your project or environment; - as usual, things that required only for running tests are put
to
test-requirements.txt.
Tox.ini
Our tox.ini describes several test environments that allow to test TaskFlow with different python versions and sets of requirements installed.
To generate tox.ini, use the toxgen.py script by first installing
toxgen and then provide that script
as input the tox-tmpl.ini file to generate the final tox.ini file.
For example:
$ toxgen.py -i tox-tmpl.ini -o tox.ini
