A ring buffer, often known as a circular queue, is a fixed-size N FIFO data structure. It can be used to transport data between asynchronous processes or to store log files. When the buffer is empty, the consumer must wait for data to be deposited; when the buffer is full, the producer must wait for data to be deposited. Create a RingBuffer API as well as an implementation that uses an array representation (with circular wrap-around).
