/**
 * \file
 * This interface provides only one function at all.
 * indexUuid will generate a uuid to the current object.
 *
 * This one is not generic enough for an interface...I
 * don't want to rely on Uuid here....The Uuid stuff is more
 * an implementation of this interface.
 *
 * An implementation of indexable::index should always return
 * an instance of class Index / or an class that implements
 * the index interface. Uuid would then be a candidate for such
 * a class.
 * 
 * \todo
 * Maybe merge hashable and indexable. Thus we might get an
 * easy way to exchange the hashing mechanism used for my
 * associative arrays.
