MJRefresh 类结构图：
MIRefreshComponent:刷新控件的基类
MJRefreshHeader：基础的下拉刷新控件(Header)
MJRefreshStateHeader:带有状态文字的下拉刷新控件
MJRefreshNormalHeader:默认的下拉刷新控件
MJRefreshGitHeader:带动图的下拉刷新控件
MJRefreshFooter：基础的下拉刷新控件(Footer)
MJRefreshBackFooter：会回弹到底部的下拉刷新控件
MJRefreshAutoFooter：会自动刷新的上拉刷新控件
MJRefreshBackStateFooter:带有状态文字的上拉加载控件MJRefreshAutoStateFooter:带有状态文字的上拉加载控件
MIRefreshBackNormalFooter:默认的上拉加载控件
MIRefreshBackGifFooter:带动图的上拉加载控件
MIRefreshAutoNormalFooter:默认的上拉加载控件
MIRefreshAutoGifFooter:带动图的上拉加载控件
