New features

• #27 - lot of changes:
  • method to add another regex builder to current regex - use add(Builder) for it.
  • unnamed group method and shortcuts for capture* methods capt(), group() and so on...
  • oneOrMore(), zeroOrMore() and atLeast(int) methods

Breaking changes:

• non backward compatibility - make Builder constructor package-private.
  Use regex() factory method instead
• non backward compatibility - change multiply(String, Integer...) method same as in original JS implementation

Improvements

• In tests:
  • replace assertTrue and assertFalse with assertThat with matchers
  • one more complex example (you can read on wiki page about it)
