These header files describe the interface for Objects, Strings, and Queues. The test.cpp file also contains tests to guarantee correctness of any implementation of these interfaces.

Implementers must adhere to the ownership rules described in the documentation for each method. Failure to do so will cause frustrating segfaults and memory leaks.

The purpose of an Object is to represent an abstract base class that any class may extend in order to get useful methods such as equals and hash. It is imperative that classes extending Object override both equals and hash.

The purpose of a String is to provide convient methods and a wrapper for when needing to use an array of characters. The String class is also an example of a class that extends Object.

A Queue is a common data structure that may be convient when needing to use an ordered list and efficiently access the front of the list.
