- marks if the value is considered to be independent of 'x'.
  Propagate into PatchFunction1 instead ad hoc checks there.

- adjust method name in PatchFunction1 to 'whichDb()' to reflect
  final changes in Function1 method names.

ENH: add a Function1 'none' placeholder function

- This is principally useful for interfaces that expect a Function1
  but where it is not necessarily used by a particular submodel.

TUT: update Function1 creation to use objectRegistry

- previously had a patch-size check, which caused a zero-sized patch
  to be "sticky" as uniform Zero regardless of what the original input
  stated (eg, "constant 0.5")

  This was caused by short-circuiting logic that circumvented reading
  on zero-size patches.

- additional debug information

- improve support for dictionary specification of constant, polynomial
  and table entries. These previously only worked properly for
  primitiveEntry, which causes confusion.

- extend table Function1 to include TableFile functionality.
  Simplifies switching and modifying content.

- easier support for non-mandatory functions.

  In some boundary conditions it can be desirable to support
  additional functions, but not necessarily require them. Make this
  easier to support with a Function1, PatchFunction1 NewIfPresent()
  selector.

- support for compatibility lookups

- harmonize branching logic and error handling between Function1 and
  PatchFunction1.

ENH: refactor a base class for Function1, PatchFunction1

- includes base characteristics, patch or scalar information

ENH: additional creation macros

- makeConcreteFunction1, makeConcretePatchFunction1Type for adding a
  non-templated function into the correct templated selection table.
  makeScalarPatchFunction1 for similarity with makeScalarFunction1

- emit "constant " and "uniform " as separate word/space combination

- this improves overall consistency and makes re-reading as a generic
  patch field behave properly when the underlying patch has zero size.

Adding tutorials and other minor changes

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.

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.

PolynomialEntry: Templated polynomial DataEntry to support all basic field types from scalar to tensor
This allows polynomial functions for e.g. velocity to be specified in the uniformFixedValue BC

Consider a linear function for Ux(t) with Uy and Uz = 0:

    inlet
    {
        type            uniformFixedValue;
        uniformValue    polynomial
        (
            ((10 0 0)   (0 0 0))
            ((100 0 0)  (1 0 0))
        );
    }
