Add support for hood.math

This commit adds support for hood.math at the University of Waterloo
using the ICC compiler.  Before compiling and running, the user's
environment should be set up with:

. /opt/intel/bin/iccvars.sh intel64

and

. /opt/intel/composer_xe_2013_sp1.1.106/mkl/bin/mklvars.sh intel64
