This is the central co-ordinator of the flask server.
It creates the app, configures it, opens the database, and starts the login manager.
It is crucial that the imports from the module are at the very end, to avoid
complications from circular imports.
It only knows where the database lives, because we passed the base directory
in sys.path[0]. As a backup, for Windows development machines, the database
location can be specified in config.py, in the form:
SQLALCHEMY_DATABASE_URI = 'sqlite:///C:\\android\\ZAPScorer\\server\\mj.sqlite'
