The "<type>Coeffs" sub-dictionary is now optional for most model parameters

except turbulence and lagrangian which will also be updated shortly.

For example in the nonNewtonianIcoFoam offsetCylinder tutorial the viscosity
model coefficients may be specified in the corresponding "<type>Coeffs"
sub-dictionary:

transportModel  CrossPowerLaw;

CrossPowerLawCoeffs
{
    nu0         [0 2 -1 0 0 0 0]  0.01;
    nuInf       [0 2 -1 0 0 0 0]  10;
    m           [0 0 1 0 0 0 0]   0.4;
    n           [0 0 0 0 0 0 0]   3;
}

BirdCarreauCoeffs
{
    nu0         [0 2 -1 0 0 0 0]  1e-06;
    nuInf       [0 2 -1 0 0 0 0]  1e-06;
    k           [0 0 1 0 0 0 0]   0;
    n           [0 0 0 0 0 0 0]   1;
}

which allows a quick change between models, or using the simpler

transportModel  CrossPowerLaw;

nu0         [0 2 -1 0 0 0 0]  0.01;
nuInf       [0 2 -1 0 0 0 0]  10;
m           [0 0 1 0 0 0 0]   0.4;
n           [0 0 0 0 0 0 0]   3;

if quick switching between models is not required.

To support this more convenient parameter specification the inconsistent
specification of seedSampleSet in the streamLine and wallBoundedStreamLine
functionObjects had to be corrected from

    // Seeding method.
    seedSampleSet   uniform;  //cloud; //triSurfaceMeshPointSet;

    uniformCoeffs
    {
        type        uniform;
        axis        x;  //distance;

        // Note: tracks slightly offset so as not to be on a face
        start       (-1.001 -0.05 0.0011);
        end         (-1.001 -0.05 1.0011);
        nPoints     20;
    }

to the simpler

    // Seeding method.
    seedSampleSet
    {
        type        uniform;
        axis        x;  //distance;

        // Note: tracks slightly offset so as not to be on a face
        start       (-1.001 -0.05 0.0011);
        end         (-1.001 -0.05 1.0011);
        nPoints     20;
    }

which also support the "<type>Coeffs" form

    // Seeding method.
    seedSampleSet
    {
        type        uniform;

        uniformCoeffs
        {
            axis        x;  //distance;

            // Note: tracks slightly offset so as not to be on a face
            start       (-1.001 -0.05 0.0011);
            end         (-1.001 -0.05 1.0011);
            nPoints     20;
        }
    }
