rather than being calculated on construction and stored as member data.

The convergence warning has be replaced with the 'convergence()' member
function which returns 'true' if the SVD iteration converged, otherwise 'false'.

wclean: added support for automatic searching up the tree for the Make directory if in a sub-directory

Provides efficient integration of complex laminar reaction chemistry,
combining the advantages of automatic dynamic specie and reaction
reduction with ISAT (in situ adaptive tabulation).  The advantages grow
as the complexity of the chemistry increases.

Two tutorial cases are currently provided:
    + tutorials/combustion/chemFoam/ic8h18_TDAC
    + tutorials/combustion/reactingFoam/laminar/counterFlowFlame2D_GRI_TDAC

the first of which clearly demonstrates the advantage of dynamic
adaptive chemistry providing ~10x speedup,

the second demonstrates ISAT on the modest complex GRI mechanisms for
methane combustion, providing a speedup of ~4x.

More tutorials demonstrating TDAC on more complex mechanisms and cases
will be provided soon in addition to documentation for the operation and
settings of TDAC.  Also further updates to the TDAC code to improve
consistency and integration with the rest of OpenFOAM and further
optimize operation can be expected.

Note: this reuses the existing storage rather than costly reallocation
which requires the initial allocation to be sufficient for the largest
size the ODE system might have.  Attempt to set a size larger than the
initial size is a fatal error.

Usage
    Example usage:
    limitU
    {
        type            limitVelocity;
        active          yes;

        limitVelocityCoeffs
        {
            selectionMode   all;
            max             100;
        }
