// DEFINITION
//
// The class Inverse_index<IC,T> constructs an inverse index for a
// given range [i,j) of two iterators or circulators of type `IC' with the
// value type `T'. The first element I in the
// range [i,j) has the index 0. Consecutive elements are numbered
// incrementally. The inverse index provides a query for a given iterator
// or circulator k to retrieve its index number. For random access
// iterators or circulators, it is done in constant time by subtracting i.
// For other iterator categories, an STL `map' is used, which results in a
// log j-i query time. A comparison operator `operator<' is needed for
// `T*'.
