Tidying up CGAL and boost inclusion. Removed the CGAL_PATH variable, using

CGAL_SRC for everything.  Changed location of CGAL_FILES "files".

Updated old meshers with new options.

in .bashrc using this environment:

~~~~~~~~~~~
export BOOST_LIB_VERSION=1_39
export BOOST_PATCH_LEVEL=_0
export BOOST_COMPILER=gcc43

export BOOST_VERSION=$BOOST_LIB_VERSION$BOOST_PATCH_LEVEL
export BOOST_ROOT=$WM_THIRD_PARTY_DIR/boost_$BOOST_VERSION

export CGAL_VERSION=3.4
export CGAL_SRC=$WM_THIRD_PARTY_DIR/CGAL-$CGAL_VERSION
~~~~~~~~~~~

and have written a script call makeCGAL to build and configure boost and CGAL:

~~~~~~~~~~~

BOOST_ARCH_PATH=${BOOST_ROOT}/platforms/${WM_OPTIONS}

cd ${BOOST_ROOT}

rm -rf ${BOOST_ARCH_PATH}

./bootstrap.sh \
    --with-libraries=thread \
    --libdir=$BOOST_ARCH_PATH/lib \
    --includedir=$BOOST_ROOT/include

if [ -r /proc/cpuinfo ]
then
    WM_NCOMPPROCS=$(egrep "^processor" /proc/cpuinfo | wc -l)
    [ $WM_NCOMPPROCS -le 8 ] || WM_NCOMPPROCS=8

    time ./bjam -j $WM_NCOMPPROCS install
else
    time ./bjam install
fi

    echo "Done boost"

    cd ${CGAL_SRC}
