typedef Assignment<Key> gtsam::DiscreteFactor::Values |
A map from keys to values TODO: Do we need this? Should we just use gtsam::Values? We just need another special DiscreteValue to represent labels, However, all other Lie's operators are undefined in this class.
The good thing is we can have a Hybrid graph of discrete/continuous variables together.. Another good thing is we don't need to have the special DiscreteKey which stores cardinality of a Discrete variable. It should be handled naturally in the new class DiscreteValue, as the varible's type (domain)

Construct from container of keys.
This constructor is used internally from derived factor constructors, either from a container of keys or from a boost::assign::list_of.
