Nested Types cause parse failures

[d-c-d]

The examples that come with the Object Pascal Handbook yield the following parse error

Failing (1)
	Expected EqualSign but found ProcedureKeyword (1)
		.\NestedClass.pas:263

The Offending file is here on github? https://github.com/MarcoDelphiBooks/ObjectPascalHandbook/tree/master/07/NestedTypes

Stripping down the code to this:

unit NestedClass;

interface

type
  TOne = class
  public
    type TInside = class
      type TInsideInside = class
      end;
    public
      procedure InsideHello;
    end;
  end;

end.

--- We still get the error

Failing (1)
	Expected EqualSign but found ProcedureKeyword (1)
		.\NestedClass.pas:145

Will need to study this some more

I manually applied the pull request https://github.com/joewhite/dgrok/pull/2 Fix the wrong look-ahead for the TypeDecl rule #2 and it fixes the above issue ( Thanks tomalla5120x ! )
