Mark Olesen 3b74512231 ENH: cleanup of Enum class

- more dictionary-like methods, enforce keyType::LITERAL for all
  lookups to avoid any spurious keyword matching.

- new readEntry, readIfPresent methods

- The get() method replaces the now deprecate lookup() method.

- Deprecate lookupOrFailsafe()
  Failsafe behaviour is now an optional parameter for lookupOrDefault,
  which makes it easier to tailor behaviour at runtime.

- output of the names is now always flatted without line-breaks.
  Thus,

     os << flatOutput(someEnumNames.names()) << nl;
     os << someEnumNames << nl;

  both generate the same output.

- Constructor now uses C-string (const char*) directly instead of
  Foam::word in its initializer_list.

- Remove special enum + initializer_list constructor form since
  it can create unbounded lookup indices.

- Removd old hasEnum, hasName forms that were provided during initial
  transition from NamedEnum.

- Added static_assert on Enum contents to restrict to enum or
  integral values.  Should not likely be using this class to enumerate
  other things since it internally uses an 'int' for its values.

  Changed volumeType accordingly to enumerate on its type (enum),
  not the class itself.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                              AVL/FIRE fpma/fpmb
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
fpma/fpmb are polyhedral formats (ASCII and BINARY).
The fpmaz/fpmbz are the same, but in compressed format.

The fpma/fpmb format can exported directly from within the FIRE GUI.
However, it is not recommended to import them directly.
Instead use the utility fire_wm_convert_file, fire_wm_convert_mesh
(or equivalents)
are used to rewrite the fpma/fpmb into the internal FIRE format.

The face-stream:

The cell-face-stream:
    nface faceId0 .. faceIdN


CAUTION:
    The FIRE faces have inward-facing normals.
    The OPENFOAM faces have outward-facing normals!

                                 AVL/FIRE flma
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The AVL/FIRE flma format is very simple, but can only be used for 1D/2D shapes
and for 3D primitive shapes.

it is fairly easy to write and to parse.
For 3D polyhedra, the cell-types are non-obvious and not easily determined
- the fpma/fpmb format is preferred for that.
