Removed sample stuff, added our own first folder with working hello world application
Update README.md
added needed libs, created new packages, cleaned up project folder.

Basically each of these packages will come out as a standalone .jar file. Think of each of them as a box in a high level view of our system. Our job now is to fill each out with classes that give it all its functionality
Created stub registration, login

Also created User object but need to consider public, private or
protected for each of the methods in the class.
Bulked out our components a little bit

Hopefully these are all correct but they seemed necessary to create a
full implementation of Sessions
