用序列化技术。CArchive。
其实保存对象，实际就是保存类成员变量。具体可参考msdn：
ms-help://MS.VSCC.v90/MS.MSDNQTR.v90.en/dv_vclib/html/1db772b1-ad55-4fcf-b133-126cca082510.htm

这涉及到C++的串行化过程。重载Doc类的Serialize函数，在其中将Doc的成员变量串行和并行化：
if (ar.IsStoring())
{
// TODO: add storing code here
ar<<m_var1<<m_var2<<m_var3;
}
else
{
// TODO: add loading code here
ar>>m_var1>>m_var2>>m_var3;
}
这里假设m_var1,m_var2,m_var3是Doc类的成员变量。记住if-else结构中的变量顺序一定要一致！
