- simplifies local toggling.
- centralize fileModification static variables into IOobject.
They were previously scattered between IOobject and regIOobject
- in specific cases it can be useful to suppress searching the instances.
For example, if one only wishes to check if a "points" is available at
the given time instance, without searching backwards through all
times.
Moved file path handling to regIOobject and made it type specific so
now every object can have its own rules. Examples:
- faceZones are now processor local (and don't search up anymore)
- timeStampMaster is now no longer hardcoded inside IOdictionary
(e.g. uniformDimensionedFields support it as well)
- the distributedTriSurfaceMesh is properly processor-local; no need
for fileModificationChecking manipulation.
