Ring buffer as specified seems incorrect

[jcs-lambda]

The specifications for a ring buffer in the example and in the tests do not make sense to me.

When a ring buffer's contents are retrieved, they should start with the oldest item and continue to the newest item.

As the spec stands, when the ring buffer is retrieved, it starts with whatever happens to be in the slot of the first item inserted, continues to the newest item, then continues with the oldest item up to the first slot.

Spec as stated:

• RingBuffer(10)
• .append(1...15)
• .get() = [11, 12, 13, 14, 15, 6, 7, 8, 9, 10]

My understanding of a ring buffer:

• RingBuffer(10)
• .append(1...15)
• .get() = [6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
