The sort sequence is now (a) numbers in parentheses, (b) integers
and decimal numbers, and (c) multidot numbers. A single period is now the
decimal symbol for numbers both inside and outside of parentheses.
(Alternate characters for the decimal symbol and the thousand-separator
symbol can be selected. This is not shown in SortTest.)

Made changes to the Data page.

Moved the flag to limit results to -1, 0, or 1 from CompareStrings() to
the constructor. These values are expected by CompareItem().

SortTest 3.0

Removed friend class statements from include
files.
