- In FreqDist.inc(), if count==0, then don't even add it to the list of   samples. - In FreqDist.Nr(), check if r is negative. - Added FreqDist.__contains__, which test whether a sample has occured. - Added type checking to UniformProbDist.__init__ - Fixed bug in UniformProbDist's calculation of the prob for each sample - In MLEProbDist, check that the freq dist has at least 1 sample - In LidstoneProbDist, check that the freq dist has at least one bin - In LidstoneProbDist, check that bins is not smaller than freqdist.B()
