Document the callback arg

[igorcov1, 2016/08/10 18:05:04]

Done.

+  RequestPinView(const std::string& extension_name,
+                 const std::string& dialog_type,

+                 const RequestPinCallback& callback);

[stevenjb, 2016/08/09 21:04:39]

Document the input params

[igorcov1, 2016/08/10 18:05:03]

Done.

[stevenjb, 2016/08/09 21:04:39]

Document new public methods

[igorcov1, 2016/08/10 18:05:03]

Done.

+  void SetCallback(const RequestPinCallback& callback);
+  void SetDialogParameters(const base::string16& error_message,
+                           bool accept_input);

[stevenjb, 2016/08/09 21:04:39]

Avoid multiple methods with the same name, it is confusing and error prone.
|dialog_type| (which needs to be documented) can always be passed as an empty
string or "".

[igorcov1, 2016/08/10 18:05:03]

Done. I've changed the dialog_type to an enum, as I don't like passing strings
around. Hopefully it's more clear now.
