SymbolNode in BAA will become BAASymbolNode and use the generalized SymbolNode from shred as a base class (or it will add it as a child) to avoid duplication of the SymbolNode in IAAM, BAA, and Build a Nucleus - BAN (https://github.com/phetsims/build-a-nucleus/issues/9#issuecomment-1045454629). This branch will be deleted once BAASymbolNode is created and used instead of the current BAA specific SymbolNode.
