Detailed Description

Generic map sorting class.

This class is used to sort a vector of integer indices into a map. This includes sorting the whole map to get highest or lowest density first, or sorting some subset, e.g. a list of peak indices. Integer indices are used because they are the most compact way of referencing a unique map location. e.g.

    clipper::Xmap<float>::Map_reference_index ix;
    std::vector<int> index;
    for ( ix = xmap.first(); !ix.last(); ix.next() )
      index.push_back( ix.index() );
    Map_index_sort::sort_decreasing( xmap, index );
