Two more standard examples for type wrapping and InternalFunction

Here are two of the test files I used to get familiar with some of the concepts I needed. I've cleaned them up and commented everything.

Adding a pull request in the hopes that the next person starting on similar problems may find them useful. Feel free to commit or reject as you like.
Honestly, I just copied that line from the other examples. I have no clue what it says or which tools use it.

If you want me to use different indentation in the file, please point me to an auto-formatter that respects the line and I'll prepare a new commit.
