Added classes to the coverage src path
Added classes to the coverage src path

Probably want to move to having my source in a src directory but that's not
something I want to do at this time. Checking coverage in ./classes will skip
over the pickles.php file (which I don't necessarily think needs tested) but
also skips over the ./vendors directory which contains some third party stuff
that doesn't have as much test coverage.
