in case of tmp misuse.
Simplified tmp reuse pattern in field algebra to use tmp copy and
assignment rather than the complex delayed call to 'ptr()'.
Removed support for unused non-const 'REF' storage of non-tmp objects due to C++
limitation in constructor overloading: if both tmp(T&) and tmp(const T&)
constructors are provided resolution is ambiguous.
The turbulence libraries have been upgraded and '-DCONST_TMP' option
specified in the 'options' file to switch to the new 'tmp' behavior.
To be used instead of zeroGradientFvPatchField for temporary fields for
which zero-gradient extrapolation is use to evaluate the boundary field
but avoiding fields derived from temporary field using field algebra
inheriting the zeroGradient boundary condition by the reuse of the
temporary field storage.
zeroGradientFvPatchField should not be used as the default patch field
for any temporary fields and should be avoided for non-temporary fields
except where it is clearly appropriate;
extrapolatedCalculatedFvPatchField and calculatedFvPatchField are
generally more suitable defaults depending on the manner in which the
boundary values are specified or evaluated.
The entire OpenFOAM-dev code-base has been updated following the above
recommendations.

This scheme is equivalent to the CoBlended scheme except that the Courant
number is evaluated for cells using the same approach as use in the
finite-volume solvers and then interpolated to the faces rather than being
estimated directly at the faces based on the flux. This is a more
consistent method for evaluating the Courant number but suffers from the
need to interpolate which introduces a degree of freedom. However, the
interpolation scheme for "Co" is run-time selected and may be specified in
"interpolationSchemes" and "localMax" might be most appropriate.
Example of the cellCoBlended scheme specification using LUST for Courant
numbers less than 1 and linearUpwind for Courant numbers greater than 10:
\verbatim
divSchemes
{
.
.
div(phi,U) Gauss cellCoBlended 1 LUST grad(U) 10 linearUpwind grad(U);
.
.
}
interpolationSchemes
{
.
.
interpolate(Co) localMax;
.
.
}
\endverbatim
Use the trace as the limiter function for both symmTensor and tensor to
bound the normal stresses rather than the shear stresses.
