Simplification of function application

[zirkel]

In IdealSimplifier.simplifyApply(EvaluatedFunctionExpression apply), there is a loop to handle the arguments to the apply.

for (int i = 0; i < numArgs; i++) {
	Simplification argumentSimplification = simplifyTree(apply
			.argument(i));
	change = change || argumentSimplification.success();
	newArguments[i] = argumentSimplification.result();
}

However, the method EvaluatedFunctionExpression.argument(int index) returns the function for index=0, and starts the function arguments at index=1. Thus, the call to this method should probably be either

apply.argument(i+1)

or else

apply.functionArgument(i)

I can make the change, I just wanted to confirm that my interpretation is correct.

Changed it to use functionArgument().
