ENH: Added new ceeateZeroDirectory utility

Uses a system/caseProperties file to select templates from
etc/caseDicts/createZeroDirectoryTemplates to enable high-level setup
of a case.

- etc/caseDicts/createZeroDirectoryTemplates
- tutorials/preProcessing/createZeroDirectory

It was not correctly interpolating faceZones which are on processor boundaries.
This caused difference between serial and parallel running. Fixes #16.

Some bcs (e.g. humidity) use an external transported field so this needs
to be registered asap.

ENH: foamHelp - added support for solvers

- Added support for solvers
- Updated use of FOAM_ABORT - old code left commented in helpBoundary.C for now...

Feature turbulence

Turbulence updates from our internal development line:
- Added DESModel base class for DES models
- Moved DES models to separate DES directory
- Added DESModelRegions function object
- Updated porousBafflePressure BC to use DataEntry class for D and I inputs
- Documentation updates

See merge request !17

For distributed data + running redistributePar some of the processors
might not have level0Edge. In this case the sync() routine should
fix this but it does require at least the master to have valid data.

- Initial code supplied by CFD Software E+F GmbH
- Refactored and integrated into the new templated Turbulence structure by
  OpenCFD
- To use the new convection scheme, add the library
  libturbulenceModelSchemes.so to the $FOAM_CASE controlDict

Object generates an indicator field for DES turbulence models to show
in which regions LES or RAS modelling is active.

SpalartAllmarasDES now derived from DESModel class

The signal handling can now be set and unset. This latter is important
for external libraries (e.g. VTK/OpenGL) that do not work with it.

Resolves bug-report http://www.openfoam.org/mantisbt/view.php?id=1918
Patch provided by Richard Jones

maxIters could be made an option input if 20 is not sufficient for
difficult cases.

The resetAMI in the cyclicAMI would go up to cyclicACMI and do the
initPatchFaceAreas again - but with already masked areas

The old version of regionSplit would hand out regions one by one. This
is a big problem when there are lots of regions - the extreme being
in the decompositionMethods, where it is used to cluster cells and most clusters
being only one cell. This rewrite uses a mesh wave to determine disconnected
regions in one go. This produced non-compact numbering which is then compacted
in a second phase.
On a 14M cell case with cyclic constraints this reduced decompose
time from 40 mins down to 5.

Before was zeroing displacement on all coupled points before
applying the displacement. This meant that we could not modify the
internal displacement on coupled points before setting the patch displacement.
Fixes #10.

Feature external coupled

- externalCoupled moved from BC to FO
- Multi-region support

Merge branch 'feature-externalCoupled' of develop.openfoam.com:Development/OpenFOAM-dev-OpenCFD into feature-externalCoupled

Conflicts:

- moved control to functionObject (from bc)
- this allows multi-region support
- see heatTransfer/chtMultiRegionFoam/externalCoupledMultiRegionHeater tut
- generalisation of streamed reading/writing of specialised bcs

ENH: potentialFoam updates migrated from internal development line

Added:
- header documentation
- pressure reference cell and value for -writep option
- removed unused createControls.H file - now uses pisoControl control structure

Feature sampled surfaces

Bounds handling for sampledSurfaces only (so not for streamlines)
