- 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
