Feature: Restoring default models
  In order to get prediction models into their initial state
  As a manager
  I need to be able to restore deleted default models

  Background:
    Given the following "users" exist:
      | username 	| firstname	| lastname | email          	|
      | manager  	| Max      	| Manager  | man@example.com	|
    And the following "role assigns" exist:
      | user    	| role    	| contextlevel	| reference		|
      | manager 	| manager		| System      	|							|
