Represents a position in a JSON value and allows moving around the JSON value. Also known as a "zipper." The cursor has a focus representing the current position being referred to by the cursor. Users may update the focus using withFocus (or the >-> alias) and move the cursor around with left, right, field, downArray, downField and up.
