Fixed Bugs: Fixed Bugs:
o MATH-1142: Improve performance of kalman gain calculation in "KalmanFilter" by
directly solving a linear system rather than computing the matrix
inverse. Thanks to Arne Schwarz.
o MATH-1181: Fixed integer overflow in KolmogorovSmirnovTest causing 2-sample test
to use exact method when the product of the sample sizes exceeds
Integer.MAX_VALUE, resulting in effectively hung execution.
