Add the p4h branch ;)

Happy Hacking!
Add prep2.
Add prep3.
Add prep4.

This includes a "super bonus" (level 42) challenge to keep the
non-beginners more entertained. Totally optional, and I won't think less
of you if you don't complete it.
Add prep5.

Classes for the class...
Add prep6.

User should understand simple module layout and how to include it.
Add prep7.

Note: if it is slow to run vagrant commands, this is because vagrant is
slow to process a complex Vagrantfile that has many machines defined. If
you destroy or halt the unused vms, and then comment them out, since
there are fewer to loop through, the vagrant operations should go
faster!
Add prep8.

The exec fun starts :)
Changed p4h to be a separate git submodule...
