Detailed Description

template<typename SetRange>
class operations_research::SetRangeIterator< SetRange >

An iterator for sets of increasing corresponding values that have the same cardinality.

For example, the sets with cardinality 3 will be listed as ...00111, ...01011, ...01101, ...1110, etc...

Dividing by c as in HAKMEMC can be avoided by taking into account that c is the smallest singleton of current_set_, and using a shift.
