Create an examples folder and use it as part of the testing process

Created by: skylerberg

It would be helpful to have example ion scripts to both help out users and enhance testing. We could have an examples/ directory with scripts in it. Each script would end with .ion and we could also have .out files to show the expected output for each script. Once we have this we could easily add an automatic test to run each of these and compare the actual output with the expected output. This type of integrations testing would add much more confidence for me than any amount of unit testing would.
