-/**
- * Double-sided tape is essentially two tapes stuck together with a shared
- * cursor.
- *
- * The main way a double-sided tape differs is that it can be flipped, allowing
- * access to another set of data.
- *
- * However, there is only one cursor, and the position of the cursor on one side
- * is the inverse of the position on the other side.
- *
- * When one side is extended, a null will be inserted into the inactive side
- * regardless of the auto-extension policy of the tape. The policy will still be
- * respected for the active side.
- *
- * All operations that refer to the tape refer to the currently active side of
- * the tape, except for flip.
- *
- * Flip refers to the entire tape for 'obvious' reasons.
- *
- * @param <T>
- *        The element type of the tape.
- *
