示例1: getValue
// getValue
// Gets the value of the number/expression at the current position
// If the current value is an integer, return it
// If it's a parenthetical expression, evaluate, and return
// evalMultiplication is a flag used to ensure multiplication happens before addition
// If true, it will handle any multiplication that is applied to the current value
// That way, what is returned to the addition function is what we actually want to add
// Parameters:
// iter - the iterator for the list of tokens
// postExpr - the postfix expression we are converting to
// evalMultiplication (input boolean) whether to evaluate multiplication, see above
// Pre-condition: expr[pos] is an int or parenthesis
// Post-condition: expr[pos] is the end of the value
// If it was an int, it's on the int
// If it was a parenthesis, it's on the end parenthesis
// If handling multiplication, it's on the last multiplied int
// postExpr has the values handled here pushed to it
