#Acme runs a testbed. They've delegated the authority to create
#experiments to all their partners. The Globotron company is one such
#partner.
#
#    Acme.experiment_create <- Acme.partner.experiment_create
#
#Globotron has delegated the authority to anyone an admin thinks is a
#'power user'.
#
#    Globotron.experiment_create <- Globotron.admin.power_user
#
#Alice and Dave are admin(s), and their friend Bob is a power user:
#
#    Globotron.admin <- Alice
#    Globotron.admin <- Dave
#
#    Alice.power_user <- Bob
#    Dave.power_user <- Bob
#
#From these credentials, it is possible to show that 
#    Acme.experiment_create <- Bob.
#
#In query.py, it show that Bob can create experiment at Acme and
# there are 2 possible solution proof
