示例1: EquationParsing

        public void EquationParsing()
        {
            string test = " 4x+1 = 102.333^2 444 theEnd";
            scanner = test;
            scanner.IgnoreWhitespace = true;
            
            scanner.Expect("4");
            Assert.AreEqual("4",scanner.Match, "Expect 4");

            Assert.Throws(typeof(InvalidOperationException), Del(() =>
            { 
                scanner.Expect("y"); 
            }),"Expect thows");

            var text = scanner.GetAlpha();
            Assert.AreEqual("x", text, "Got correct text");
            
            scanner.ExpectChar('+','-');
            Assert.AreEqual("+", scanner.Match, "Got correct operator");
            scanner.ExpectNumber();
            Assert.AreEqual("1", scanner.Match, "Got correct number");
            
            // skip the =
            scanner.Next(2);

            text = scanner.GetNumber();
            Assert.AreEqual("102.333", scanner.Match, "Got correct number");

            scanner.AssertNotFinished();
            scanner.ExpectChar('^');
            scanner.ExpectNumber(); // 2
            scanner.ExpectNumber(); // 444
            
            text = scanner.GetAlpha();
            
            Assert.AreEqual("theEnd", text, "Got correct number");
            Assert.IsTrue(scanner.Finished);
            scanner.Undo();
            Assert.AreEqual("444", scanner.Match, "Undo returned correct data for current");
            scanner.Next();
            Assert.AreEqual('t',scanner.NextChar,"In correct position");
            text = scanner.GetAlpha();
            Assert.AreEqual("theEnd", scanner.Match, "Backing up resulted in the previous match");

        }
