- The existing ':' anchor works for rvalue substitutions
  (Eg, ${:subdict.name}), but fails for lvalues, since it is
  a punctuation token and parse stops there.

STYLE: update dictionary documentation

- can be used directly from within an application or function-object.
  Makes it available for dictionaries.

- suppress error messages that appear with zsh.
  According to unset(1p), 'unset -f' unsets a function.
  If the function was not previously defined, this is a no-op.
  This is similar for zsh, but there it emits a warning if the
  function was not previously defined.

- avoid 'local' in functions sources from etc/bashrc.
  ksh does not support this.

- use 'command' shell builtin instead of 'type'.
  Seems to be more consistent between shell flavours.

- POSIX specifies '-c' for counting the number of matching lines,
  so we can just use that instead of 'wc' in wmake

- if called from the top-level project directory ($WM_PROJECT_DIR)
  default to using {applications,src} directories. This avoids
  erroneous linking of etc/codeTemplates and avoids the lengthy
  scanning of the tutorials directory

- use InfoSwitch to disable, or via static method.

- respect the state of the argList banner when deciding to emit
  initialization information. Can otherwise end up with unwanted
  output rubbish on things like foamDictionary and foamListTimes.

- patch from Bernhard Gschaider

- nested classes can't be forward declared and thus less flexible
  than desired

- patch from Bernhard Gschaider

- consistent use of watchIndex vs watchFd

See merge request !102

Fixes #420.

The typical topology is the one where boundary faces share non-consecutive
points (checkMesh reports this as 'Number of faces with non-consecutive shared points')
This is handled by no-extruding any of the vertices of both faces. Fixes #391.

- use similar semantics as used for dealing with metis, scotch

- This can be used as a convenient alternative to comparing against end().
  Eg,

    dictionaryConstructorTable::iterator cstrIter =
        dictionaryConstructorTablePtr_->find(methodType);

    if (cstrIter.found())
    {
        ...
    }
  vs.
    if (cstrIter != dictionaryConstructorTablePtr_->end())
    {
        ...
    }

- reduce the amount of checking.
  Equivalent logic to what HashTable has.

- remove stray canonicalSize declaration

- 1st problem arises when there are edges, but edgeNormals is empty.
  The UIndirectList fails (zero elements, non-zero addressing)

- further problem occurs if there is a mismatch in the number of edges
  and edges normals (incorrect indexing on loop).

- can be useful with compiling additional OpenFOAM programs
  that use FOAM_USER_APPBIN, FOAM_USER_LIBBIN for their build,
  to avoid conflicts with the normal user bin/lib files.

- or to force relocation of FOAM_SITE_APPBIN, FOAM_SITE_LIBBIN
  during packaging of OpenFOAM

- consistent with use of FOAM_SOLVERS, and reduces reliance on the FOAM_APP
  env variable

- had occasional remnant use of FOAM_SRC

Fixed by setting flag which then gets queried by Time. Fixes #420.

- useful for builds that don't use the ThirdParty directory at all
