version on a switch.  See #867

By default the code will use the same form as previous versions

To use the experimental version integrated from openfoam.org commit
da787200 set the info switch in the controlDict:

    InfoSwitches
    {
        experimentalDdtCorr 1;
    }

- when the iso-surface (eg, a cut plane, or distanceSurface) passes
  exactly through the cell centre, zero-sized triangles can occur.
  These should be merged away.

- change "\%" -> "%" in plain string

- minor change to pruning of lagrangian fields

- use "min:xxx" for consistency with other outputs

- link CGAL (clang version) without reference to mpfr,gmp libraries

- use offset address in printStack for Darwin as well

- alternative handling of feexcept on Darwin

STYLE: more consistent use of dimensioned Zero

- use floor/truncate instead of round. Backport of changes in the
  develop-pre-release branch.

- affects random integer ranges.
  Simpler to extend the range by one and floor (truncate) instead of
  rounding using odd intervals.
