We have gtest C++ based unit tests, but it's not hooked up on all platforms and build systems (notably it doesn't build on Windows yet, or the Xcode build).  Even if it's only for tests now, it certainly seems like it could be integrated into other aspects of the SB API later by someone else.

I don't really like the program dumping thing because it's adding a bunch of layers on top of what I really want to test, which is just the argument parsing.  The shell gets in the way for example, and you can't guarantee that if you call <program> <command-line> that this will end up in a call to Args::SetCommandString(<command-line>) because the shell might have done something.

We need to test that Args::SetCommandString(<command-line>) with known values of <command-line>, parses and tokenizes the way we expect.  I can remove the C++ from the public API, but I kind of think that having an SBArgs is the best way to do this.
