5e22dad52e Added non-central T to distributions.hpp. 
Updated generic_mode to use additive stepping where appropriate.
Improved NC-Beta PDF calculation and termination conditions.
More or less got non-central T finished off: quantiles now work, PDF and mode almost correct.
Fixed typo in toms748_solve.hpp
Updated NC-T tests to include mode and quantile.

6dd0f0d42c Corrected range to permit df == 2 
and Added comment(-ed code) about mode with df < 2.

12df5b2419 Updated non central beta cdf to accept both x and 1-x on input: allows greater accuracy when using these routines in the non central F and T distributions. 
Updated non central F to take advantage of this.
Added some non central distributions to the graph generator.

Updated tests to match.

Update tests to cope with other platforms.
Disabled a few tests that can never pass.

ccb9b8c656 Added a modification to the extreme value distribution. This allows the specification 
of a sign to determine the minimum or maximum case. Note that the original extreme value
distribution refers to the maximum case. This class will need some work. Discussion
leaned towards the use of an enumerated parameter rather than a real-typed sign
for the determination of min/max case.

8e24be2ffe Added stubs for new distributions. These are neither fully tested nor documented and, 
in some cases, incomplete. However, migrating them into the sandbox will hopefully
help motivate their completion.

fe3db87cc4 Change concepts classes so they can be used when there is no long double support. 
Added first cut of the non-central chi squared distribution.
Removed almost all occurrences of real_cast: replaced with calls to the truncation/rounding functions instead.

fc5f875671 Fixes #1454. 
Previous fix was incomplete, so added new tests, confirmed problem report, and added fixes.

All the tests now compile cleanly with g++ -pedantic -Wall -Wno-long-long (checked with gcc-4.4.1 and 3.4.4).

605c55e00e Added workarounds for IBM xlc C++: the compiler can't resolve an overloaded function template to a function pointer unless the template arguments are explicitly provided. 
Fixed some bugs uncovered by the above workaround: some forward declarations didn't match the actual definition!
Hopefully fixed remaining Sun compiler issues: mostly fixed by above fixes anyway.

69031ebe9d Added static assertion to catch use of long double function overloads when BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS is defined. 
Made sure that if BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS is defined, then no long double overloads are actually instantiated by the tests.
