so that the specification of the name and dimensions are optional in property dictionaries.

Update tutorials so that the name of the dimensionedScalar property is
no longer duplicated but optional dimensions are still provided and are
checked on read.

The implementation now correspond to the definitions in the readily
available reference:

http://personalpages.manchester.ac.uk/staff/david.d.apsley/specturb.pdf

in which a large number of linear and non-linear models are presented in
a clean and consistent manner.  This has made re-implementation and
checking far easier than working from the original references which anyway
are no longer available for the LienCubicKE and ShihQuadraticKE models.

turbulenceModels/LES/dynamicLagrangian: Added the Lagrangian averaged form of the dynamic Smagorinsky eddy-viscosity SGS model for LES

turbulenceModels/RAS/SSG: Added Speziale, Sarkar and Gatski pressure-strain based Reynolds-stress turbulence model

Thanks to Jan-Niklas Klatt for analysing problems with and correcting
the implementation and testing corrections to the model proposed by
Furst.

This is as temporary fix pending the completion of the selectable thermal transport layer

Now using the Daly-Harlow generalized gradient diffusion model

Changed the tutorials/incompressible/pimpleFoam/channel395 to demonstrate the WALE model

The old separate incompressible and compressible libraries have been removed.

Most of the commonly used RANS and LES models have been upgraded to the
new framework but there are a few missing which will be added over the
next few days, in particular the realizable k-epsilon model.  Some of
the less common incompressible RANS models have been introduced into the
new library instantiated for incompressible flow only.  If they prove to
be generally useful they can be templated for compressible and
multiphase application.

The Spalart-Allmaras DDES and IDDES models have been thoroughly
debugged, removing serious errors concerning the use of S rather than
Omega.

The compressible instances of the models have been augmented by a simple
backward-compatible eddyDiffusivity model for thermal transport based on
alphat and alphaEff.  This will be replaced with a separate run-time
selectable thermal transport model framework in a few weeks.

For simplicity and ease of maintenance and further development the
turbulent transport and wall modeling is based on nut/nuEff rather than
mut/muEff for compressible models so that all forms of turbulence models
can use the same wall-functions and other BCs.

All turbulence model selection made in the constant/turbulenceProperties
dictionary with RAS and LES as sub-dictionaries rather than in separate
files which added huge complexity for multiphase.

All tutorials have been updated so study the changes and update your own
cases by comparison with similar cases provided.

Sorry for the inconvenience in the break in backward-compatibility but
this update to the turbulence modeling is an essential step in the
future of OpenFOAM to allow more models to be added and maintained for a
wider range of cases and physics.  Over the next weeks and months more
turbulence models will be added of single and multiphase flow, more
additional sub-models and further development and testing of existing
models.  I hope this brings benefits to all OpenFOAM users.
