/**
  * This class implements a classifier that takes a {@link Word} as input and
  * generates Boolean features representing the capitalizations of the words
  * in a [-2, +2] window around the input word.  The generated features
  * consist of the capitalization (as read from {@link Word#capitalized}) of
  * the input word as well as the capitalizations of the two words before the
  * input word in the sentence and the capitalizations of the two words after
  * the input word in the sentence.  If any of those words do not exist, the
  * corresponding feature isn't generated.
  *
  * <p> This class's implementation was automatically generated by the LBJ
  * compiler.
