在啃protocol部分，有兴趣的一起来吧，也请mechiland多指点

我想，这部分是此框架的精华之一了，而且学习此部分的代码，应该非常有助于我们开展其他AJAX后台框架（如DWR），乃至xml<->javabeans框架（如xstream）的代码学习工作。

均为protocol下的类图，各位先参考。

我通过Basic的例子，关注simpleService.randomComplexUser的marshal过程，以分析协议对复杂对象的解析和处理。

下面是返回的XML例子：

<buffalo-reply>
<map>
	<type>net.buffalo.demo.simple.ComplexUser</type>
	<string>name</string>
	<map>
		<type>net.buffalo.demo.simple.Name</type>
		<string>firstName</string>
		<string>John</string>
		<string>middleName</string>
		<string>M</string>
		<string>familyName</string>
		<string>Smith</string>
	</map>
	<string>friends</string>
	<list>
		<type>[net.buffalo.demo.simple.ComplexUser</type>
		<length>2</length>
		<map>
			<type>net.buffalo.demo.simple.ComplexUser</type>
			<string>name</string>
			<map>
				<type>net.buffalo.demo.simple.Name</type>
				<string>firstName</string>
				<string>Friend</string>
				<string>middleName</string>
				<string>H</string>
				<string>familyName</string>
				<string>Johnson</string>
			</map>
			<string>friends</string>
			<list>
				<type>[net.buffalo.demo.simple.ComplexUser</type>
				<length>2</length>
				<ref>0</ref>
				<map>
					<type>net.buffalo.demo.simple.ComplexUser</type>
					<string>name</string>
					<map>
						<type>net.buffalo.demo.simple.Name</type>
						<string>firstName</string>
						<string>Michael</string>
						<string>middleName</string>
						<string>J</string>
						<string>familyName</string>
						<string>Jordon</string>
					</map>
					<string>friends</string>
					<list>
						<type>[net.buffalo.demo.simple.ComplexUser</type>
						<length>2</length>
						<ref>3</ref>
						<ref>0</ref>
					</list>
				</map>
			</list>
		</map>
		<ref>6</ref>
	</list>
</map>
</buffalo-reply>

Buffalo.BOCLASS的设计和考虑让人惊喜，学习中……
