Detailed Description
Class for loading and storing a fixed Model.
The class CFeatureStochasticModel implements all functions from
the interface CAbstractFeatureStochasticModel,
therefore it maintains a CStateActionTransitions
for every state-action pair. For storing the CStateActionTransitions
object a 2 dimensional array is used. The class provides additional
functions for setting the probability of a transition. If the
transition doesn't exist, a new transition object is created with
the specified probability, otherwise the probability is just set.
For the semi-MDP case, the duration of the transition can be
specified as well. The given probability is then added to the
existing transition probability and the duration factors are all
adopted so that there sum is again one. The model can only be used
for loading, saving and directly setting the probabilities, its not
able to learn anything from a learning trial.

If the action is a multistep action, a CSemiMDPTransition is
returned, otherwise a CTransition object. The transition
gets initialised with the given values.
