OAOO for the trackPointQuery and trackSequenceQueryNN Reporter classes.

C++ has this marvellous thing called templates, which allows for almost
1% of the power of writing source code at compile-time; in this
particular case, that 1% is enough, as it allows us to generalize over
the predicate for ordering in queues with a template class.

Move reporters into reporter.h.  The template class needs to be in
there anyway; the pointQueryReporter will soon gain a template class
analogue for Ollie's use case; and then there's just the Radius
reporter.
