AST Format

Parsing code:

int answer = 6 * 7;

outputs following AST (the positions of each AST entry have been removed to reduce size):

[
    {
        "type": "GlobalVariableDeclaration",
        "defType": {
            "type": "Type",
            "modifier": [],
            "name": "int"
        },
        "name": "answer",
        "value": {
            "type": "BinaryExpression",
            "operator": "*",
            "left": {
                "type": "Literal",
                "value": 6,
            },
            "right": {
                "type": "Literal",
                "value": 7,
            },
        }
