bug fix : enum without name & add --version option

[cheoljoo]

Additional function : --version

• add --version arguments in command line
• I think that modified version will be 0.3

Bug : What is the problem

• we have the error when we use enum without name.

  enum {
  AAAAAAA,
  BBBBBBB,
  };

• Error Message

  [1133] WARN-enum: nameless enum ['enum', '{', 'AAAAAAA', ',', 'BBBBBBB', ',', '}']

• Changed Code

  • This error generates when it is not defined the key of dictionary.
    • So define "empty" name as a default value when enum does not have the name.
  • super().init('enum', header_enum['name']) -> super().init('enum', header_enum.get('name',empty))
  • output

    
    @startuml
    enum empty {
    AAAAAAA
    BBBBBBB
    }
