-------------------------------------
I'll merge in the changes from JENA-29 now.
I'll update the incorrect license text too. Sorry, it appears that in moving it
to the bottom of the file, I seem to have pasted the wrong text in. The

> In QueryIterSort, the sorting of the contents of an Iterator<Binding> is done
> in memory, using Arrays.sort. This can be problematic where the set to be
> sorted is large. A possible solution could be to use an external, disk-backed
> algorithm. A hybrid approach may be better, whereby we attempt the in-memory
> sort, but when the number of bindings encountered goes over a certain number,
> resort to the disk-backed variant.
