Add ridiculous command line exercise; character generator

This is a stub of a D&D character generator that takes it's input
entirely from command line options.

It will use defaults if you run the program with no command line
options:

`./character_generator`

Or you can run it with options, like so:

`./character_generator -p "Mr. FooBar" -n "Lady Blackbird" -s 22 -d 50
-o 30 -i 900 -w 10 -h 89 -c -g`
