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.

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.
// Polynomial functions and interpolation do evaluate to label
// Instead evaluate a scalar and convert to label as appropriate
// makeDataEntryType(PolynomialEntry, label);
// makeDataEntryType(CSV, label);
// makeDataEntryType(Table, label);
// makeDataEntryType(TableFile, label);

It is better to declare the namespace of each function in the C file
rather than "open" the namespace as this may lead to inconsistencies
between the declaration in the H files and definition in the C file.
Now solvers return solver performance information for all components
with backward compatibility provided by the "max" function which created
the scalar solverPerformance from the maximum component residuals from
the SolverPerformance<Type>.
The residuals functionObject has been upgraded to support
SolverPerformance<Type> so that now the initial residuals for all
(valid) components are tabulated, e.g. for the cavity tutorial case the
residuals for p, Ux and Uy are listed vs time.
Currently the residualControl option of pimpleControl and simpleControl
is supported in backward compatibility mode (only the maximum component
residual is considered) but in the future this will be upgraded to
support convergence control for the components individually.
This development started from patches provided by Bruno Santos, See
http://www.openfoam.org/mantisbt/view.php?id=1824
by ensuring tetBasePtIs is called on all processors, even for those with
0 cells. Also use unique communicator for globalMeshData to avoid data
transfer interference.
Resolves bug-report http://www.openfoam.org/mantisbt/view.php?id=1792
Avoids problems with overlapping communicationbetween these reductions
and the calculation of deltaCoeffs. This is a temporary fix while code
reorganizations are undertaken to ensure the globalMeshData is updated
before deltaCoeffs are requested.
