简单行编辑器：简单行编辑器要求实现行插入和行删除，以一行为操作目标，这里使用了双链表，一行为一个Node，整个双链表链表为一篇文档的形式来存储。算法使用了KMP算法来实现查找，且支持"*"、"?"等通配符。-Simple line editor: Simple line editor insert rows and rows required to achieve removed to a behavioral operational objectives, where the use of the double-linked list, an act a Node, the entire doubly linked list is stored in the form of a document. Algorithm uses the KMP algorithm to achieve the look, and support the " *" , " ?"　And wildcards.
