/**
  * This class implements a classifier that takes a {@link Word} as input and
  * generates features representing the prefixes and suffixes of the input
  * word.  The generated features include prefixes of length 3 and 4 and
  * suffixes of lengths 1 through 4 of the input word only.  If any of those
  * words do not exist, the corresponding features aren't generated.
  *
  * <p> This class's implementation was automatically generated by the LBJ
  * compiler.
