* Update minitwit & improve testing for examples
* Related to #1945
* Re-works minitwit to be installed and run as:
pip install --editable .
export FLASK_APP=minitwit.minitwit
export FLASK_DEBUG=1
flask initdb
flask run
* added flaskr and minitwit to norecursedirs
* tests not properly run when using pytest standards
* see: http://stackoverflow.com/questions/38313171/configuring-pytest-with-installable-examples-in-a-project
* Both flaskr and minitwit now follow pytest standards.
* Tests can for them as `py.test` or `python setup.py test`
* Update minitwit readme
* updates the instructions for running
* Fixes for updating the minitwit example
- This reverts the changes to the *docs/* (I will file separate PR).
- Running the app is now: `export FLASK_APP=minitwit` & `flask run`
(After installing the app)
* Remove unnecessary comma from flaskr/setup.py
