    optionally specified [file].

foamRunTutorials now accepts two arguments:
-test : Preferentially execute Alltest, if present, over Allrun.
-skipFirst : Skip Alltest/Allrun at the top level to prevent recursion

Added because some tutorials are not dependent on controlDict and take
a long time.

gperftools comes with a profiler. It should be installed in ThirdParty.
Then link the executable to libprofiler.so, run it and view the output
using kcachegrind.
