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

- 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.

- as of v1706
  extractFromSurfaceCoeffs { ... } is an optional subdictionary

- replace duplicate code with global bounds enums and Enum

- if the enum name is not found, then warn and return the default.

- use typedefs and new features/methods
- file-scope template to avoid code duplication.

- make the purpose of various parts clearer

- can now suppress prefixing an underscore to leading digits.

- allows configuration without an environment variable.
  For compatibility still respect FOAM_SIGFPE and FOAM_SETNAN
  env-variables

- The env-variables are now treated as true/false switch values.
  Previously there was just a check for env exists or not, but this
  can be fairly fragile for a user's environment.

- allows configuration without an environment variable.
  For compatibility still respect MPI_BUFFER_SIZE env-variable.

ENH: add degToRad() multiplier (useful for scalar fields)

- use degToRad() functions throughout instead of scattered local solutions

- use 1024 instead of 1000 since it will be changed internally to 1024 anyhow.

- use separate constructor for ignore-case option (cf. wordRe treatment)

- constructors/destructor now inline.

- make some IOobject writing routines non-templated.

- relocate more IOobject methods into the IOobjectI.H
  (generally cleanup the main header).
