Javadoc
This class is used to produce a state feature vector from an
burlap.mdp.core.oo.state.OOState by iterating
over the objects, generating a double array for each object, and concatenating the reslting vectors into one vector.
You specify the ordering of the vectorization by specifying the order of the OO-MDP object classes, and which
DenseStateFeatures to use for objects of their class.
If multiple objects of a class exist, then they will be unpacked in the order defined by the
burlap.mdp.core.oo.state.OOState.
