1st commit of skew_normal to boost sandbox, but failures in mode TODO.

[SVN r76720]
Added an alternate method to compute the mode, which needs careful review. Substituted all explicitly written constants for the boost counterparts. Also updated the driver file to compute the mode and fixed a minor bug.


[SVN r76806]
Add forwarding/type promoting/policy enabled functions to owens_t.hpp.
Add test data files.
Update tests to use test data.

[SVN r76811]
Extended the precision of the spot values in the test for Owens T function.

[SVN r76823]
Many constants have been substituted with the newly added in trunk.
Did some changes to the mode computation routine, mostly the starting
guess.


[SVN r76935]
Added a verification routine for Owen's T function and included it into
the tests. Further did a small cosmetic change to Owen's T function.


[SVN r77151]
Add Jamfile to aid testing.

[SVN r77169]
Regenerate test data to exclude values that have cancellation errors.

[SVN r77226]
Fix Linux error tolerances and fix missing {} warnings.

[SVN r77233]
Fix build failures with arbitrary precision types.

[SVN r77249]
Modified T7 verification routine to avoid underflows. Fixed speed issues
with the tests.


[SVN r77263]
Fix pow call to use ADL.

[SVN r77361]
Fixed the spot-on tests for the skew normal distribution. Included
dedicated long double versions of some routine for Owen's T function.
Fixed an overflow issue in Owen's T reference routine. Reworked some of
the test for Owen's T and the skew normal distribution.


[SVN r77740]
Fix compiler errors in example.
Fix test failures.
Fix owens_t code to use mpl-based dispatch to select correct implementation.

[SVN r77776]
Removed tabs and fixed the indentation to work with spaces only.


[SVN r77882]
General update for multiprecision support:
Added new accelerated version of T1.

[SVN r78043]
Add tentative arbitrary precision version of T2.
Add special cases from Owen's original paper as test cases.

[SVN r78062]
Add some special case handling.
