- Eg, "${scope/name}" to be supported with this.

- generic means of holding ranges of substring iterators

- makes the purpose clearer.
  In some places, string::resize() is even simpler.

- use C++11 string::back() in preference to str[str.size()-1]

- this now appears to be the more common use case.

- the 'protect' inputMode is used to supply defaults.
  If an entry already exists, it should act as a no-op without any
  side-effects whatsoever.

- installed under /usr/include/scotch/scotch.h

ENH: obtain fallback value for SCOTCH_VERSION from the header

COMP: add support for metis, scotch static libraries (eg, EasyBuild)

- Resolve ambiguity by using the following rules:

  1) starts with '/'  =>  absolute file-system path
  2) starts with './' or '../'  =>  file-system path relative to CWD
  3) otherwise treat as relative to the case

STYLE: allow write access to headerClassName

- mostly associated with forgotten quotes around "(abd|def)" ...

- Address different potential problems:

      (key) { key1   entry1; }
      (key) { key1   entry1; };    // <- Note trailing ';'
      (key) entry2;

Feature streams cleanup

See merge request !127

STYLE: checkMesh: remove duplicate writeSets entry from header (resolves #293)

See merge request !125

- clear error flags. Special handling for igzstream.

- resets the output buffer completely - implementing what rewind was
  likely meant to have accomplished for many use cases.

STYLE: OSHA1stream reset() for symmetry. Deprecate rewind().

- use allocator class to wrap the stream pointers instead of passing
  them into ISstream, OSstream and using a dynamic cast to delete
  then. This is especially important if we will have a bidirectional
  stream (can't delete twice!).

STYLE:

- file stream constructors with std::string (C++11)

- for rewind, explicit about in|out direction. This is not currently
  important, but avoids surprises with any future bidirectional access.

- combined string streams in StringStream.H header.
  Similar to <sstream> include that has both input and output string
  streams.

Feature external file coupler

See merge request !126

- do not recheck the abort after it has been triggered once.
  This reduces the output clutter and file checks.

- since the cpu/sys information is invariant, it doesn't make much
  sense to emit by default at every time-step.

- With many processors, the number of entries becomes quite large.

  New controlDict InfoSwitches: "writeSlaves", "writeRoots".

- added an explicit print, but only report profiling to the log
  file from master process.

  We don't wish to overwrite any profiling that was conducted during
  the simulation. Besides which, we don't have a proper Time object
  for handling the write nicely either.

- add note in BuildIssues about the I_MPI_CC variable, which is needed
  when building with Intel-MPI and gcc/clang.

  This additional setting is needed since the changes needed to solve
  the issue of building scotch with Intel-MPI and icc (issue #434)
  means that mpiicc is now being used as the wrapper when compiling
  scotch.

- have the FOAM_MPI short name for INTELMPI start with 'impi-' instead
  of just the version number.
  Intel-MPI is often installed as /opt/intel/impi/4.1.3.049, which
  results in 'FOAM_MPI=4.1.3.049' and the mpi flavour is lost.
  Prefix these cases with 'impi-'

- Added for transition purposes only in 1612 but can now be removed.
