Find the original code for the 'cubature' package at

    http://ab-initio.mit.edu/wiki/index.php/Cubature

plus information why the 'adapt' package had to be abandoned and that
'cubature' is based on the same original algorithm of Genz and Malik,
but using free and GPLed software.

We should not bemoan the loss of the 'adapt' package, 'cubature' and
'R2cuba' are worthy successors for adaptive quadrature.
