c++ STL 007 容器（list）

list

模版原型：
template < class T, class Alloc = allocator > class list;

是一个双向链表

Lists are sequence containers that allow constant time insert and erase operations anywhere within the sequence, and iteration in both directions.

List containers are implemented as doubly-linked lists; Doubly linked lists can store each of the elements they contain in different and unrelated storage locations. The ordering is kept internally by the association to each element of a link to the element preceding it and a link to the element following it.

They are very similar to forward_list: The main difference being that forward_list objects are single-linked lists, and thus they can only be iterated forwards, in exchange for being somewhat smaller and more efficient.

	/**
		迭代器功能begin，end，rbegin，rend，cbegin，cend，crbegin，crend使用是stl容器中通用的功能，可以参考vector内容
		empty 是否为空列表
		size 列表尺寸
		max_size 当前环境可存档最大元素个数
		front，back 返回第一个、最后一个元素的引用
		back与end区别： 返回值不同，一个是引用，一个是迭代器。
			Returns a reference to the last element in the list container.
			Unlike member list::end, which returns an iterator just past this element, 
			this function returns a direct reference.

//assign Assign new content to container
//Assigns new contents to the list container, replacing its current contents, and //modifying its size accordingly.
