class Resource
# Special class to represent any entity of a type. This is used for
# type-wide grants or checks. It is basically so {AllOfType} can
# have an entity rather than a nil.
#
# Wildcards or null objects typically have somewhat strange semantics, and
# this is no exception. It will compare as eql? and == to any object that
# has the same type attribute.

# Create a wildcard entity that will compare as equal to
def initialize(type)

# Always returns true; this wildcard is "equal" to any object.
# return [Boolean] true
