It allows to become shadow of Person, Computer and Software Instance.

Pylint is not for chickens.

Called method is setting up response code 503 in case of cache being empty. So

(and not tested)

Don't hack just because you want pyflakes to pass.

Also update doc

It is required now to call vifib_solve_automatically alarm after

Check divergence (for calculating and building) really often and while checking only move to one of possible states (solved or diverged).

For diverged ones try rarely to solve divergence automatically.
