How to use the edge-parser.expressions.BinaryExpression function in edge-parser

     * Instead of using `parser.generateEdgeExpression`, we make use of
     * `generateAcornExpression`, since we do not want to process
     * `Indentifer` expressions as per the normal parsing logic
     * and just want to extract it's name.
