/*! Functions like Matlab's dblquad() for 2D integrals.  Wrapper for cubature by Steven Johnson.
 
The cubature code is used for double integration.  It replaces iterated use of
a single-variable adaptive rule as in Matlab's dblquad.  cubature.{h|c} by Johnson
is based on HIntLib by Rudolf Schuerer as well on GSL itself.  cubature is GPLed.
