### FeaturesInWindow

    public FeaturesInWindow(java.lang.String namePrefix,
                            int leftBoundaryOffset,
                            int rightBoundaryOffset,
                            java.util.regex.Pattern featureRegex,
                            boolean includeBeginEndBoundaries)

Parameters:
  `namePrefix` - what to prepend to feature names
  `leftBoundaryOffset` - left boundary of the window (e.g. -1 means include the previous word
  `rightBoundaryOffset` - right boundary for this window (e.g. 1 means include the current position, but not the next
  `featureRegex` - add only for features matching this (null = always match
  `includeBeginEndBoundaries` - ignored

### FeaturesInWindow

    public FeaturesInWindow(java.lang.String namePrefix,
                            int leftBoundaryOffset,
                            int rightBoundaryOffset)

  equivalent to
  `FeaturesInWindow((namePrefix, leftBoundaryOffset, rightBoundaryOffset, null, true);`
