+ 2.0 (Major improvements)
+ ---
+ Fixed bug where singleton events are dropped. (Tom)
+
+ Added eval method so distribution could be passed in rathar then
+ allocated durring each call. Left old interface in place but modified
+ it to use the new eval method. Also made numfeats a class level
+ variable. (Tom)
+
+ Fixed cases where parameters which only occured with a single output
+ weren't getting updated. Ended up getting rid of pabi and cfvals
+ structures. These have been replaced with the data for a single event,
+ double[] modelDistribution, and this is used to update the modifiers
+ for a single event and then updated for each additional event. This
+ change made it easier to initialize the modleDistribution to the
+ uniform distribution which was necessary to fix teh above problem.
+ Also moved the computation of modelDistribution into it's own routine
+ which is name eval and is almost exactly the same as GISModel.eval w/o
+ doing the context string to integer mappings. (Tom)
+
+ Made correction constant non-optional. When the events all have the same
+ number of contexts then the model tries to make the expected value of the
+ correction constant nearly 0. This is needed because while the number of
+ contexts may be same it is very unlikly that all context occur with all
+ outcomes. (Tom)
+
+ Made nextIteration return a double which is the log-likelihood from
+ the previous itteration. At some point there isn't enough accuracy in
+ a double to make further iterations useful so the routine may stop
+ prematurly when the decrease in log-likelihood is too small. (Tom)
