The README is really good for users of the library. I was looking for a description of the algorithm, though,
and I couldn't find any. Does anyone know what algorithm this library implements? (e.g. a literature reference would be helpful). I'm familiar with a couple of PQ implementations based on skip-lists: Sundell & Tsigas and Linden & Jonsson--but this library doesn't seem to be based on any of them.
