/**
 * A finite state machine for text filters using regular expressions.

 * newlines). States are subclasses of the `State` class. Transitions consist
 * of regular expression patterns and transition methods, and are defined in
 * each state.
 *
 * The state machine is started with the `run()` method, which returns the
 * results of processing in a list.
