A fourth Index value is added to support the 7.x and 11.x beta distribution.
The parameters for beta have changed since 2000.x (5.x). A fourth Index value is added to support the 7.x and 11.x beta distribution.
The extreme value constant is deprecated. It is included for Crystal Ball 2000.5 (5.5) compatibility and is replaced by cbDfaMinExtreme and cbDfaMaxExtreme in later versions of Crystal Ball l.
A new distribution type, betaPERT (cbDfaBetaPert), is added in Crystal Ball 7.3.
