Log Message:
Update to 1.6.0

Changelog:
## JFlex 1.6.0
- Unicode 7.0 is supported.
- In %unicode mode, supplementary code points are now handled properly.
  . Regular expressions are now code-point based, rather than code-unit/
    char based.
  . Input streams are read as code point sequences - properly paired
    surrogate code units are read as a single character.
  . All supported Unicode properties now match supplementary characters
    when Unicode 3.0 or above is specified, or when no version is
    specified, causing the default Unicode version, Unicode 7.0 in this
    release, to be used.
- New \u{...} escape sequence allows code points (and whitespace-separated
  sequences of code points) to be specified as 1-6 hexadecimal digit values.
- Characters in matches printed in %debug mode are now Unicode escaped
  (\uXXXX) when they are outside the range 32..127.
- fixed bug #127, detect javadoc class comment when followed by annotation(s)
- removed the "switch" and "table" code generation options
- By default no InputStream constructor is included in the generated
  scanner.  The capability to include one is deprecated and will be
  removed in JFlex 1.7.

## JFlex 1.5.1 (Mar 21, 2014)
- fixed bug #126, problem calling ./jflex start scripts
- fixed bug #125, minor documentation flaws
- further documentation and website updates
- JFlex now reports the correct version string
- added support for CUP2 with %cup2 switch, based on patch by Andreas Wenger

## JFlex 1.5.0 (Jan 21, 2014)
- the "switch" and "table" code generation options are deprecated
  and will be removed in JFlex 1.6
- the JFlex license has been changed from GPL to BSD.
- updated JFlex to CUP version 0.11a.
- changed the build from Ant to Maven.
- JFlex now mostly conforms with Unicode Regular Expressions UTS#18
  Basic Unicode Support - Level 1.  Supplementary code points (above
  the Basic Multilingual Plane) are not yet supported.
- new meta characters supported: `\s, \S, \d, \D, \w, \W`.
- nested character sets now supported, e.g. [[[ABC]D]E[FG]]
- new character set operations supported: union (e.g. [A||B]), intersection (e.g.
  [A&&B]), set-difference (e.g. [A--B]), and symmetric difference (e.g. \ 
[A~~B]).
- the meaning of the dot (".") meta character has been changed from \ 
`[^\n]` to
  `[^\n\r\u000B\u000C\u0085\u2028\u2029]`. Use the new `--legacydot` option to
  cause "." to be interpreted as `[^\n]`.
- new `\R` meta character matches any newline:
  `"\r\n" | [\n\r\u000B\u000C\u0085\u2028\u2029]`.
- new option --noinputstreamctor to not include an InputStream
  constructor in the generated scanner.
- %include <file> can now be used in the rules section (bug #116)
- fixed bug #105 & #106 (yychar and zzAtBOL should be reset for nested input \ 
streams)
- fixed bug #107 (could not match input for empty string matches.)
- fixed bug #110 & #118 (properly update zzFin when reallocating zzBuffer)
- fixed bug #114 (noncompileable scanner generation when default locale is Turkish)
- fixed bug #113 (zzEOFDone not included with pushed nested stream state)
- fixed bug #103 (can't build examples/java/)
- fixed bug #104 (impossible char class range should trigger syntax error)
