Performs the actual decision based on a property of the state. If the quick lookup table has been initialized
then the decision is taken straight from it. If not then the supplied reference to the decision tree at this
point is used to find the outcome by scanning over its children.

@param  state the {@link com.thesett.aima.state.State} to decide on.

@return a {@link DecisionTree} to continue the decision process with.
