pointsInstance.
For now also dump topology related sets to pointsInstance since otherwise
paraFoam cannot see them (only looks at first 'sets' directory when searching
back)
- 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.
- can use 'XX.empty()' instead of 'XX.size() == 0', 'XX.size() < 1' or
'XX.size() <= 0' or for simpler coding.
It also has the same number of characters as '!XX.size()' and /might/ be
more readable
- many size checking had 'XX.size() > 0', 'XX.size() != 0', or 'XX.size() >= 1'
when a simple 'XX.size()' suffices
- boundBox::invertedBox is useful for initializing our own calculations
- NOTE treeBoundBox::greatBox is still in place, since it uses GREAT
instead of VGREAT. If this is only historical, we can drop it.
