Detailed Description

The purpose of this type is to be able to apply STL algorithms like |std::find|, in situations where the values compared are really integers but not actually all stored in memory. This is achieved by having the iterators themselves containing the values, so that |operator*| just delivers the value stored. To be of any interest, the comparison function should have some special context dependent meaning, probably involving table lookup. It is a major inconvenience that, since we are comparing integers, the values compared against must be accessible in this way, in other words stored in the same table that we are (implicitly) searching. For this reason these iterators are currently unsused by atlas, and might well remain so forever.

It is assumed that U is a (typically unsigned) integral type.
