Scene Feature Flags

FeatureFlags is a set-like object that holds the flags. There are three ways to establish a set of flags:

The FeatureFlags constructor takes one or more params, each of which is a flag from the lists defined below. If the argument feature_flags is not passed when creating a scene (i.e. feature_flags=None), then the default set will be used.
