Constructor needed an additional JavaDoc comment
* Added new tests for ProbabiltiyBasedAlgorithmTest
(testWeightFunctionExtendAndEllipticalProbMap,
testConvexHullTransformation, testCautiousOfMethodCalculation)
* Added JavaDoc comments
Created a test 'KalmanFilterTest' just to test if the method that can
