Support for parenthesized type declarations

[rlankfo]

I had several parenthesized interface type declarations and noticed they weren't showing up in the puml output.

Examples)
Works:

type Foo interface {
  Foo()
}
type Bar interface {
  Bar()
}

Not working:

type (
  Foo interface {
    Foo()
  }
  Bar interface {
    Bar()
  }
)

I'll take a look at this. Thanks for reporting it.

Thanks. If you could provide some direction I wouldn't mind taking a crack at a PR.

Actually I would have to see how the AST represents this specific problem. Let me make a couple of tests to see if I can suggest a COA. Thanks for this and sorry for the delays in my responses. I think I have to hook some notifications in this repo. I only see these updates if I come to github.

I just took a look at this. In the fileparser/class_parser.go near to line 320 the code assumes the dec.Specs array will only contain 1 element. I have never seen the declarations as you posted in this issue and of course never ran into this case. If you wrap the code from 321 to 370 around a for loop range on each Spec you will solve this issue. :)
