Patch contributed by Bruno Santos:
 - "etc/config.sh/CGAL":
   - Indented the contents of the recently added if block.
   - Added comment about using system versions.
   - Library paths are now only added if the respective version is not "boost-system" and "cgal-system".

 - "src/renumber/Allwmake":
   It now relies on the previous file to get the version for
   Boost (the same way as in "makeCGAL"). This is so that it will also
   build "SloanRenumber" if "boost_version" is set to "boost-system".

 - "applications/utilities/mesh/generation/Allwmake":
   It now also relies on the script "config.sh/CGAL" to get the
   version for CGAL. If "cgal_version" is set to "cgal-system", it
   will now also build "foamy*Mesh" utilities and respective
   libraries.

This change brings OpenFOAM into line with the standard matrix
addressing in other C++ libraries for better interoperability.

The row-start pointer array provided performance benefits on old
computers but now that computation is often cache-miss limited the
benefit of avoiding a integer multiply is more than offset by the
addition memory access into a separately allocated array.

With the new addressing scheme LUsolve is 15% faster.

Update online documentation http://openfoam.github.io/Documentation-dev/html/

The particular rotation sequence is specified via the enumeration:

    //- Euler-angle rotation sequence
    enum rotationSequence
    {
        ZYX, ZYZ, ZXY, ZXZ, YXZ, YXY, YZX, YZY, XYZ, XYX, XZY, XZX
    };

and provided as an argument to the constructor from Euler-angles

    //- Construct a quaternion given the three Euler angles:
    inline quaternion
    (
        const rotationSequence rs,
        const vector& angles
    );

and conversion to Euler-angles:

    //- Return a vector of euler angles corresponding to the
    //  specified rotation sequence
    inline vector eulerAngles(const rotationSequence rs) const;

Provides '(i, j)' element access and general forms of inner and outer
products, transpose etc. for square and rectangular VectorSpaces.

VectorSpaces default to be column-vectors as before whereas row-vectors
may be represented as 1xn MatrixSpaces.  In the future it may be
preferable to create a specializations of VectorSpace for column- and
maybe row-vectors but it would add complexity to MatrixSpace to handle
all the type combinations.

Tensor is now a 3x3 specialization of MatrixSpace.

Sub-block const and non-const access is provided via the
'.block<SubTensor, RowStart, ColStart>()' member functions.  Consistent
sub-block access is also provide for VectorSpace so that columns of
MatrixSpaces may be accessed and substituted.

These new classes will be used to create a more extensive set of
primitive vector and tensor types over the next few weeks.

Foam::direction is an unsigned type which makes it easier for the
