Uncaught exception when using short command line parameter.

[Sqeaky]

When we pass a command line parameter shorter than 4 chars and not the word "help" this happens:

./Mezzy_Tester asdf
Uncaught exception of type std::exception made it to main. it says:
basic_string::substr: __pos (which is 5) > this->size() (which is 4)

Instead, this should be failing if the argument is invalid then the usage/help message should be displayed. If the argument is valid it should be processed as normal.

@hlayne35 This might be an easy one if you want to try.

I tried to build Mezz_Test so I could look for the bug, and CMake pooped itself. I reset my git branches and pulled the master, making sure all old files were gone, but Jagati keeps having errors? Below are some of the error gibberish and the CMake logs.
