+ "Erf/Erfc": Use a rational function approximation accurate to 53-bits
of precision.
+ This replaces the use of the regularized gamma functions P and Q and
increases accuracy
+ at extreme limits of the function. Execution speed is improved.
+ Functionality is ported from the Boost C++ library.

+ "InverseErfc": Support full range of [0, 2]. This lowers the supported
+ minimum value from 2^-53 to double min value. Execution speed is
improved.
+ Functionality is ported from the Boost C++ library.

"RegularizedBeta": Detect edge cases for arguments that can be
evaluated by
exploiting properties of the regularized beta function.
