## What does it do?
A _Gap Buffer_ is simply a list of characters, similar to a normal string, with
the added twist of splitting it into two side: the prefix and suffix, on either
side of the cursor. In between them, a gap is left to allow for quick
insertion at the cursor.
Moving the cursor moves the gap around the buffer, the prefix and suffix getting
shorter/longer as required.
