In cpplint, permit Dodxygen C++ annotations, which come after members, e.g.
  int var; //!< Brief description after the member
or
  int var; ///< Brief description after the member

Cf. http://www.stack.nl/~dimitri/doxygen/manual/docblocks.html#memberdoc

Currently, cpplint accepts comments after members, cf.
http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Implementation_Comments#Implementation_Comments
and it accepts also the doxygen comments of the type "///" (followed by a new line) and
"/// " (followed by a comment). Only the Doxygen annotations, which come
after members are rejected, which is fixed by this patch.
