Changeset 80 for trunk/EventBenchCore/src/de/ugoe/cs/eventbench/models/TrieBasedModel.java

Message:

• added getProbability() to de.ugoe.cs.eventbench.models.IStochasticProcess and implementing classes
• added getEvents() to de.ugoe.cs.eventbench.models.IStochasticProcess and implementing classes
• changed getProbability() of subclasses of de.ugoe.cs.eventbench.TrieBasedModel? such that the probability is not zero if the context length is higher than the order of the model, but rather the probability of the suffix of the length of the order, i.e., for a 2nd-order model context(X1,X2,X3,X4) becomes context(X3,X4)
