Changes to combinatorial:
Jul 01 2002 Replaced about two-thirds of the calls to sort with partial_sort.
This should result in a more efficient program. Also introduced
two error objects combinatorial_range_error and
combinatorial_sequence_disorder. [Phil Garofalo]
Jul 02 2002 Added reverser adapter, removed references to greater<T>() because
requirements stipulate that only < need be supported by the
containter elements. Replaced calls to min_element_greater_than
and max_element_less_than with min_element_if and max_element_if
respectively. [Phil Garofalo]
Changes to minmax.hpp:
Changed erroneous min_value references to max_value.
