Create UML and definitions in Part 1

[tijcolem]

Part 1. Add in the pdf for UML and definitions. Is there are way to use UML directory in GitHub using markdown? Adding static files like pdf really isn't great. I can check.

1. (5 points) What are three ways modern Java interfaces differ from a traditional OO interface design that
   describes only function signatures and return types to be implemented? Provide a Java code example of each.
2. (5 points) Describe the differences and relationship between abstraction and encapsulation. Provide a Java
   code example that illustrates the difference.
3. (10 points) Draw a UML class diagram for the FNPS simulation described in part 2. The class diagram should
   contain any classes, abstract classes, or interfaces you plan to implement to make the system work. Classes
   should include any key methods or attributes (not including constructors). Delegation or inheritance links
   should be clear. Multiplicity and accessibility tags are optional. Design of the UML diagram should be a team
   activity if possible.
