- provide a static profiling::print(Ostream&) method to output
  values to a log file.

- For example, decomposePar use multiple simultaneous Times.
  So permit multiple initialization without a warning. (issue #157)

BUG: memInfo not activated by -profiling option (fixed #157)

mapNearestAMI: move normalisation to AMIMethod.

Avoids cells shared among processors to be counted multiple times and having
weights > 1.

This is now handled inside snappyHexMesh with the keepPatches setting.

Fixes wallBoiling mentioned in #141

snappyHexMesh filters out zero-sized patches so no more createPatches.
Fixes part of #152

- broken by commit 2027059b (2016-03-09) where the pTraits
  nComponents type was changed from int to Foam::direction

for initialising 'complex' bcs. Instead now 'clone' from p. Fixes #153.

- value corresponds to the max memory when the corresponding profiling
  is started.
  Only used when the top-level profiling has memInfo active.

- memInfo is disabled by default, since the new maxMem functionality
  otherwise adds overhead with every call.

since growing single cells just makes the zoneing inconsistent with the
surface intersections (so you don't have a patch when converting surface
intersections to baffles)

- needs more refinement, but provides the general idea.

- this option overrides any controlDict settings as a convenient means
  to selecting profiling without messing with the controlDict.

- provide Profiling::writeNow() to emit profiling for utilities that
  don't have any natural time increment mechanism to trigger it.
