# This example shows an example of reasoning about a role's parameters.  There
# are 4 principals StateU, Bob, Mark, Maryann, Joe, and Jan.  StateU wants to
# establish a set of founding alumni based on the year of graduation.  On
# graduation each alum has previously been issued a credential parameterized
# with their major and graduation year.  StateU sets up a policy that says that
# a principal is a founding alum if they graduated in 1960, 1961, or 1963 in
# either mathematics or psychology.  One assumes there was some kind of NCAA
# suspension in 1962.  This policy is expressed in Credential 1.
#
# Credentials 2, 3, 4, 5, and 6 each assign a diploma credential to Bob (a 1961
# mathematics degree), Mark (a 1965 mathematics degree), Joe (a 1961 zoology degree), Maryann (a 1962 psychology degree), and Jan (a 1960 psychology degree)
#
# The attached ./run_query file asks if each of these principals are favored
# alums, and only Bob and Jan are.
