Interpolate a single-point in (x,Q2), given x/Q2 values and subgrid indices.

Todo:: Make an all-PID version of interpolateQ and Q2?

The key function to be overridden in derived classes: the subgrid and x/Q2 index lookup (and their caching) are done centrally in the Interpolator base class so do not need to be re-implemented in each flavour of interpolator.

Implements LHAPDF::Interpolator.
