Improved accuracy and testing of the inverse hypergeometric functions.

Added Noncentral Chi Squared Distribution.

Added Noncentral Beta Distribution.

Added Noncentral F Distribution.

Added Noncentral T Distribution.

Added Exponential Integral Functions.

Added Zeta Function.

Added Rounding and Truncation functions.

Added Compile time powers of runtime bases.

Added SSE2 optimizations for Lanczos evaluation.

Added Policy based framework that allows fine grained control over function
behaviour.

Breaking change: Changed default behaviour
for domain, pole and overflow errors to throw an exception (based on
review feedback), this behaviour can be customised using Policy's.

Breaking change: Changed exception thrown
when an internal evaluation error occurs to boost::math::evaluation_error.

Breaking change: Changed discrete quantiles
to return an integer result: this is anything up to 20 times faster than
finding the true root, this behaviour can be customised using Policy's.

Polynomial/rational function evaluation is now customisable and hopefully
faster than before.

Added performance test program.

Moved Xiaogang Zhang's Bessel Functions code into the library, and brought
them into line with the rest of the code.

Added C# "Distribution Explorer" demo application.

Implemented the main probability distribution and density functions.

Implemented digamma.

Added more factorial functions.

Implemented the Hermite, Legendre and Laguerre polynomials plus the spherical
harmonic functions from TR1.

Moved Xiaogang Zhang's elliptic integral code into the library, and brought
them into line with the rest of the code.

Moved Hubert Holin's existing Boost.Math special functions into this
library and brought them into line with the rest of the code.

Implement preview release of the statistical distributions.

Added statistical distributions tutorial.

Implemented root finding algorithms.

Implemented the inverses of the incomplete gamma and beta functions.

Rewrite erf/erfc as rational approximations (valid to 128bit precision).

Integrated the statistical results generated from the test data with
Boost.Test: uses a database of expected results, indexed by test, floating
point type, platform, and compiler.

Improved lgamma near 1 and 2 (rational approximations).

Improved erf/erfc inverses (rational approximations).

Implemented Rational function generation (the Remez method).

Implement gamma/beta/erf functions along with their incomplete counterparts.

Generate high quality test data, against which future improvements can
be judged.

Provide tools for the evaluation of infinite series, continued fractions,
and rational functions.

Provide tools for testing against tabulated test data, and collecting
statistics on error rates.

Provide sufficient docs for people to be able to find their way around
the library.
