 * \class Index
 *
 * A class describing an Index type, such as "Index of Names".
 * Different Index types are used in split Indices
 *
 * An Index has a name and a shortcut notation. It uses a
 * user-specifiable GUI colour. All these can be set and
 * queried.
 *
 * \class IndicesList
 *
 * A class containing a vector of all defined indices within a
 * document. It has methods for outputting a '|'-separated string 
 * of all elements, and for adding, removing and renaming elements.
