This structure is more convenient to add support for other shells, e.g. zsh, fish etc.

noSlip is equivalent to fixedValue with a value of (0 0 0) but is
simpler to specify e.g.

     upperWall
     {
         type            noSlip;
     }

movingWallVelocityFvPatchVectorField: Updated to obtain the velocity field from the dimensionedInteralField
rather than by "lookup" from the database.

To see the different behavior of flow through and around the blockage
change D in constant/fvOptions:

        // D 100;  // Very little blockage
        // D 200;  // Some blockage but steady flow
        // D 500;  // Slight waviness in the far wake
        D 1000; // Fully shedding behavior

For example the sinusoidal motion of the floating object in the
potentialFreeSurfaceFoam/oscillatingBox tutorial is now specified thus

    floatingObject
    {
        type            fixedNormalInletOutletVelocity;

        fixTangentialInflow false;

        normalVelocity
        {
            type            uniformFixedValue;
            uniformValue    sine;
            uniformValueCoeffs
            {
                frequency 1;
                amplitude table
                (
                    (   0     0)
                    (  10 0.025)
                    (1000 0.025)
                );
                scale     (0 1 0);
                level     (0 0 0);
            }
        }

        value           uniform (0 0 0);
    }

rather than using

    floatingObject
    {
        type            fixedNormalInletOutletVelocity;

        fixTangentialInflow false;

        normalVelocity
        {
            type            oscillatingFixedValue;
            refValue        uniform (0 1 0);
            offset          (0 -1 0);
            amplitude       table
            (
                (   0     0)
                (  10 0.025)
                (1000 0.025)
            );
            frequency       constant 1;
        }

        value           uniform (0 0 0);

tutorials/compressible/rhoPimpleFoam/ras/angledDuct: Updated for change in U boundary condition update order

Function1 is an abstract base-class of run-time selectable unary
functions which may be composed of other Function1's allowing the user
to specify complex functions of a single scalar variable, e.g. time.
The implementations need not be a simple or continuous functions;
interpolated tables and polynomials are also supported.  In fact form of
mapping between a single scalar input and a single primitive type output
is supportable.

The primary application of Function1 is in time-varying boundary
conditions, it also used for other functions of time, e.g. injected mass
is spray simulations but is not limited to functions of time.

    Templated sine function with support for an offset level.

        \f[
            a sin(2 \pi f (t - t_0)) s + l
        \f]

    where

    \vartable
        a       | Amplitude
        f       | Frequency [1/s]
        s       | Type scale factor

    Example for a scalar:
    \verbatim
        <entryName> sine;
        <entryName>Coeffs
        {
            frequency 10;
            amplitude 0.1;
            scale     2e-6;
            level     2e-6;
        }
    \endverbatim

    Example for a vector:
    \verbatim
        <entryName> sine;
        <entryName>Coeffs
        {
            frequency 10;
            amplitude 1;
            scale     (1 0.1 0);
            level     (10 1 0);
        }

PV4FoamReaders: Updated to build with ParaView-5.0.0
paraFoam: Updated to load PV4FoamReaders for ParaView-5.0.0

Currently this is experimental but if it becomes clear that ParaView-4
and ParaView-5 are and will remain consistent with respect to readers
the plan is to rename

PV4 -> PV

or

PV4 -> PV45 if it is assumed that PV6 may need to be different.

e.g.

    inlet
    {
        type                flowRateInletVelocity;
        massFlowRate        0.2;
        extrapolateProfile  yes;
        rho                 rho;
        rhoInlet            1.0;
        value               uniform (0 0 0);
    }

to avoid name conflicts with these primitive names in the OpenFOAM namespace

Removed inconsistent binary output.
Removed unused and IO-inconsistent functions.
Simplified the handling of backward-compatible constant value:
    Removed the unnecessary CompatibilityConstant,
    Updated Constant and DataEntryNew to handle constant value construction.

This ensures the U boundary conditions are updated before the explicit
parts of the stress are evaluated.
