/** \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.
