Support vertical ports

[Siccity]

xNode should at least provide some sort of vertical port support.

Proposal: InputAttribute and OutputAttribute gets another parater vertical. In NodeEditorGUILayout, add VerticalInput and VerticalOutput drawing functions. In NodeEditor, check for the vertical property and skip drawing them them till last. Perhaps cache port attributes in private dictionary on recompile to increase performance.

I would like to have this feature. Are there any plans to implement this anytime soon?

I am specifically looking for a framework that supports this, but unfortunately, it seems hard to come by for some reason.
