/** \class AlignableIndexer
 *
 *  Class to store a list of index functions.
 *
 *  A counter is a pointer to a function that returns the number of an
 *  alignable based on its id.
 *  The number of an alignable is given by its position within its parent.
 *  User gets a counter using its structure type via AlignableIndexer::get(type).
 *  Each sub-system has its own concrete counter class implementation.
