Changes in this version include:
New features:
+o MATH-1066: Added Bessel functions of the first kind, based on NetLib implementation. Thanks to Brian Wignall.
+o MATH-1180: Method to create a sequence of integers (in "o.a.c.m.util.MathArrays").
+o MATH-1172: New class "SimpleCurveFitter": Boiler-plate code to allow fitting of
+ a user-defined parametric function.
+o MATH-1173: New classes "TricubicInterpolatingFunction" and "TricubicInterpolator" to
+ replace "TricubicSplineInterpolatingFunction" and "TricubicSplineInterpolator".
o MATH-1166: New classes "BicubicInterpolatingFunction" and "BicubicInterpolator" to
replace "BicubicSplineInterpolatingFunction" and "BicubicSplineInterpolator".

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.
o MATH-1178: Fixed example in userguide ("stat" section). Thanks to Dmitriy.
o MATH-1175: Fixed inverse cumulative probability of 0 in "LaplaceDistribution". Thanks to Karsten Loesing.
o MATH-1174: Fixed a problem with too thin polygons considered to have infinite size.
