	The ANTLR-generated concrete syntax tree (CST) takes up much more memory than the parsed .fir file. By using a Listener, we can construct the FIRRTL AST live with CST construction and null out the CST as we consume pieces of it. Not only does this improve performance, it drastically reduces max memory use for the parser.
