以下是频繁用到的Sqlite函数，内容格式相对固定，封装一下有助于提高开发效率（^_^至少提高Codeeer的效率了）
而且，我发现Sqlite中文资料比较少，起码相对其他找起来要复杂些，服务一下大众~
我没有封装读取部分，因为数据库读取灵活性太大，封装起来难度也大，而且就算封装好了，也难以应付所有情况，还是建议根据实际情况设计代码逻辑。
解释下，为啥代码中的注释基本都用英文写了，因为这段时间在学双拼- -。可是还不太熟悉，打字超慢，而且Code的时候容易打断思路，好在~英文不多，而且这些都看不懂的话你……你要向我解释一下你是怎么一路学到数据库的 0。0

这里要说明下，因为存在多字段同时插入的情况（何止存在，很普遍- -。没见过谁的数据库像意大利面条一样）
在这里设计了Insert结构用以储存字段和值的关系（曾考虑过用数组的办法实现，可是那玩意不太方便调用，瞅着挺抽象的，不太好用，如果有更好的建议，欢迎留言~）
