consistency with UList/List and so that functions which take a UPtrList
argument can also be called for PtrList.

functionObjects are now in the functionObjects namespace so "abort" no
longer causes a name-clash.

tutorials/multiphase/reactingTwoPhaseEulerFoam/RAS/wallBoiling/system/fvSolution: Updated to improve stability

Set the environment variable "FOAMY_HEX_MESH" to build foamyHexMesh,
e.g. in ~/.OpenFOAM/dev/prefs.sh

FOAMY_HEX_MESH=yes

functionObjects: Moved into the functionObjects namespace and rationalized and simplified failable construction

Rather than requiring each functionObject to handle failed construction
internally (using the active_ flag) the static member function "viable"
is provided which returns true if construction of the functionObject is
likely to be successful.  Failed construction is then handled by the
wrapper-class which constructs the functionObject,
e.g. "OutputFilterFunctionObject".

EulerDdtScheme: evaluate dimensioned internal field expressions rather than primitive field expressions
Ensures dimension consistency and simplifies the expressions

  - .org is the file extension for emacs org-mode as well
  - .orig is more to the point (.org isn't always recognized as "original")
  - .original is too long, although more consistent with the convention
    of source code file naming

GeometricField: Renamed internalField() -> primitiveField() and dimensionedInternalField() -> internalField()

These new names are more consistent and logical because:

primitiveField():
primitiveFieldRef():
    Provides low-level access to the Field<Type> (primitive field)
    without dimension or mesh-consistency checking.  This should only be
    used in the low-level functions where dimensional consistency is
    ensured by careful programming and computational efficiency is
    paramount.

internalField():
internalFieldRef():
    Provides access to the DimensionedField<Type, GeoMesh> of values on
    the internal mesh-type for which the GeometricField is defined and
    supports dimension and checking and mesh-consistency checking.

In order to simplify expressions involving dimensioned internal field it
is preferable to use a simpler access convention.  Given that
GeometricField is derived from DimensionedField it is simply a matter of
de-referencing this underlying type unlike the boundary field which is
peripheral information.  For consistency with the new convention in
"tmp"  "dimensionedInteralFieldRef()" has been renamed "ref()".

CrankNicolsonDdtScheme: Use the new GeometricField constructor from DimensionedField and boundary FieldField

Non-const access to the internal field now obtained from a specifically
named access function consistent with the new names for non-canst access
to the boundary field boundaryFieldRef() and dimensioned internal field
dimensionedInternalFieldRef().
