Mark Olesen 06147dabe7 ENH: more flexible handling of FOAM_IORANKS 
- accept plain lists (space or comma separated) as well as the
  traditional OpenFOAM lists. This simplifies argument handling
  with job scripts.

  For example,
     simpleFoam -ioRanks 0,4,8 ...
  vs
     simpleFoam -ioRanks '(0 4 8)'  ...

  It is also possible to select the IO ranks on a per-host basis:

     simpleFoam -ioRanks host  ...

- expose rank/subrank handling as static fileOperation methods

Test that -ioRanks selections perform as expected and that sub-rank
selection is also doing the correct thing.

For example,

mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks host
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '(0 3 14)'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks 14,15,2,0,10,15,0,0,0,
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,10'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,11'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,14'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,15'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,12,115'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,10,12,115'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks host -pick '1,2,3,4'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -pick '2,4,6,8'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3' -pick '2,4,6,8'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,4' -pick '2,4,6,8'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,6' -pick '2,4,6,8'
mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,6' -pick '2,4,6,8'
