ef6a5b791a Added support for infinite degrees of freedom. 
Correct some error messages (and made quantile produce the correct complemented version by forwarding the function string to the detail:: code).

There  are still some confusing variable names.

4be8acfe68 Fix numerical stability problem in incomplete beta: ibeta_fraction2 sometimes has catastrophic cancellation errors when a and b are large and x is near 1.
