- added obj surfaceWriter
- don't bother with prepended field names on obj and stl surfaceWriter.
It fills the disk and suggests differences where there are none.
- change system/controlDict to use functions {..} instead of functions (..);
* This is internally more efficient
- fixed formatting of system/controlDict functions entry
- pedantic change: use 'return 0' instead of 'return(0)' in the applications,
since return is a C/C++ keyword, not a function.
