TransparentNode class abstract

TransparentNode refers to those node who have zero rendering content iteself, and are expected to be unwrapped for its children during rendering.

TransparentNodes are only allowed to appear directly under EquationRowNodes and other TransparentNodes. And those nodes have to explicitly unwrap transparent nodes during building stage.
