"""Support for simplified access to data on nodes of type omni.graph.tutorials.Tokens

This is a tutorial node. It exercises the feature of providing hardcoded token values in the database after a node type has
been initialized. It sets output booleans to the truth value of whether corresponding inputs appear in the hardcoded token
list.
