SlotableNode<T extends EquationRowNode?> class abstract

SlotableNode is those composite node that has editable EquationRowNode as children and lay them out into certain slots.

SlotableNode is the most commonly-used node. They share cursor logic and editing logic.

Depending on node type, some SlotableNode can have nulls inside their children list. When null is allowed, it usually means that node will have different layout slot logic depending on non-null children number.
