- provide no_topology() characteristic to avoid triggering potentially
expensive mesh connectivity calculations when they are not required.
- remove/deprecate unused pointField references from the renumber
methods. These appear to have crept in from outer similarities
with decompositionMethod, but have no meaning for renumbering.
- remove/deprecate various unused aggregation renumberings since these
have been previously replaced by pre-calling calcCellCells, or
using bandCompression directly.
- make regionFaceOrder for block-wise renumbering optional and
treat as experimental (ie, default is now disabled).
The original idea was to sort the intra-region and inter-region faces
separately. However, this will mostly lead to non-upper triangular
ordering between regions, which checkMesh and others don't really like.
ENH: add timing information for various renumberMesh stages
ENH: add reset of clockTime and cpuTime increment
- simplifies section-wise timings
ENH: add globalIndex::null() and fieldTypes::processorType conveniences
- provides more central management of these characteristics
- on large memory systems (eg, 6TB) the process information
exceeds an 'int' range, so adjust parsing of the /proc/..
to use int64
ENH: update/modernize OSspecific system information
ENH: minor update of profiling code
- std::string, noexcept, lazier evaluations
STYLE: use direct call of memInfo
