All submissions should have Javadoc comments NO COMMENT = NO CREDIT! Comments should include annotations for parameters and return types at the least. The code and Javadoc comments should have an outcome corresponding to the documentation in the index.html file in the doc subfolder. Using the Java Naming conventions, create the following(in the to-do list):

This entire software package is the product of shapely figures, whose website is located at www.shapelyfigures.net. This should be reflected in the overall package collection. In addition, the software development team needs the package to contain the following:

TO DO	Given
An interface called cube geom (1)	Class: Parallelepiped a class for parallelepipeds
A class called cube (2)	Class: RectPrism rectangular prism class
	Interface: RectPrismGeom geometric API
	Class: PrismUser main class using prism objects

The following classes are programmed

(1) The cubes geometry, in the cube geom interface, is extended from the rectangular prism geometry interface that is used by rectangular prisms to calculate their Volumes and Surface Areas. The interface, named cube geom, has one method, get volume, that overrides its parents definition this method is NOT abstract!

(2) The class for cubes has its methods call corresponding methods of the superclass, i.e., its constructor calls its parents constructor; and its sides measurement can be written or read from its parents accessor/mutator methods (any one pair would do, but we should be consistent).
