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.
