- using 'nil' type to write geometry only, in the future we could fallback to 'null'
writer and hook in arbitrary formats from surfMesh
- IOobject gets writeEndDivider() static method
- regIOobject: don't re-register an unregister object on rename/assignment
- Hasher: split-off HasherInt with uint32_t specializations
- IOobject: writeBanner/writeDivider return Stream for easier chaining.
... also dropped some namespace bracketing while I was at it.
- removed the previously added fileName type(), isDir(), isFile() methods.
- added optional bool parameter to isFile() function to explicitly
enable/disable the check for gzip files.
- fixed minor bugginess where the default usage of isFile() would result in
false positive matches.
- be slightly more stringent and use isDir() and isFile() instead of
exists() function when we actually know the expected type.
- exists() = forward to OSspecific exists(...)
- isDir() = forward to OSspecific dir(...)
- isFile() = forward to OSspecific file(...)
- IOobjectComponents() - split into instance, local, name following rules
set out for IOobject.
- added IOobject(path, registry, ...) constructor that uses
fileName::IOobjectComponents(). This hides the complexity we otherwise need.
* new -srcDoc option to display doxygen-processed source code
* display standard options -help/-doc/-srcDoc at end of usage
* consolidate code when writing IOobject headers
* drop writeLogbanner and add optional bool to writeBanner
* minor formatting changes
