       my $lexer = Compiler::Lexer->new($options);
           create new instance.  You can create object from $options in hash reference.

           optionslist

           filename
           verbose : includes token of Pod, Comment and WhiteSpace
       $lexer->tokenize($script);
           get  token  objects includes parameter of 'name' or 'type' or 'line' and so on.  This method requires

       $lexer->set_library_path(['path1', 'path2' ...])
           set libraries path for reading recursively. Default paths are @INC.

       $lexer->recursive_tokenize($script)
           get hash reference like { 'module_nameA' => [], 'module_nameB' => [] ... }.  This method requires per
           source code in string.
