/*ASTFunctionCallNode represents a function call in the code. It is a subclass
 * of both ASTExpressionNode and ASTStatementNode. This is because setting a
 * variable to the returning value from a function call (e.g. x=foo()) is 
 * considered an expression, where as a function call on its own (e.g. foo()) is
 * a statement. It overrides the print function
 * The ASTFunctionCallNode keeps track of:
 *              -the id of the function (the function's name)
 *              - the arguments as a list
