/**
* \file reflist.h
* The fast reflection list stores reflections in an RB-tree indexed
* by the Miller indices h, k and l. Any reflection can be found in a
* length of time which scales logarithmically with the number of reflections in
* the list.
*
* A RefList can contain any number of reflections, and can store more than
* one reflection with a given set of indices, for example when two distinct
* reflections are to be stored according to their asymmetric indices.
*
* There are getters and setters which can be used to get and set values for an
* individual reflection. The reflection list does not calculate any values,
* only stores what it was given earlier. As such, you will need to carefully
* examine which fields your prior processing steps have filled in.
