/**
 * The abstract class about cursors which iterate tokens.
 *
 * This class has 2 abstract methods.
 *
 * - `current: Token | Comment | null` ... The current token.
 * - `moveNext(): boolean` ... Moves this cursor to the next token. If the next token didn't exist, it returns `false`.
 *
 * This is similar to ES2015 Iterators.
 * However, Iterators were slow (at 2017-01), so I created this class as similar to C# IEnumerable.
 *
 * There are the following known sub classes.
 *
 * - ForwardTokenCursor .......... The cursor which iterates tokens only.
 * - BackwardTokenCursor ......... The cursor which iterates tokens only in reverse.
 * - ForwardTokenCommentCursor ... The cursor which iterates tokens and comments.
 * - BackwardTokenCommentCursor .. The cursor which iterates tokens and comments in reverse.
 * - DecorativeCursor
 *     - FilterCursor ............ The cursor which ignores the specified tokens.
 *     - SkipCursor .............. The cursor which ignores the first few tokens.
 *     - LimitCursor ............. The cursor which limits the count of tokens.
 *
