69273dca61 fixed too long first step in fixed Runge-Kutta integrators. 
This change is similar to the one done two years ago for adaptive step sizes integrator.

9d14fe21a4 Added proper checking of expected exception in FastMath tests. 
Some of the new functions trigger exceptions in the data range used for
tests (overflows near range end, divisions by zero). The FastMath
implementation throws compatible exception in the same cases, this is
now tested correctly.

a67f0a33e6 Added all Java 8 StrictMath methods to FastMath. 
This change allows FastMath to remain compatible with newer Java
versions, despite it stiil requires only Java 5 to compile and run.

2a59e0ef4b Recovered debugging method that were removed in the previous commit. 
The methods are useful and the warning about them being unused could be
solved with an annotation.

e9464c0a6d MATH-1151 
New interface "ValueAndJacobianFunction" (to allow separate evaluation
of either quantity) is a precondition for lazy evaluation (and is enforced
by raising an exception early rather than wait for a failed cast).

Unit tests showing that the current implementation fails on some
special values (infinities). Other descriptive statistics values
are probably similarly affected.

f25a61670e Modified KolmogorovSmirnovTest cdf computation to use the Pelz-Good 
approximation (per Simard-L'Ecuyer) for n > 140.  Removed R reference tests, as
our implementation is now different (but should be more accurate)
for the n values covered by the tests.
Also added a PI_SQUARED constant to MathUtils.
