百度地图API（一）
开题
百度地图API已经做了好久了，自己一个人做完的这个项目，一直想记录的，拖延症爆发，一直到现在，而且前面MVC还没写完，主要是卡在授权，底层和页面功能都明白了，但是就是授权，整个项目的开始没搞懂，也够郁闷的，也就把MVC放放，一边看，一边写吧，先把API写完~
百度地图控件
项目是用的WPF，地图控件用的到WPF的UserControl，结构如下
其中BaiduMap_WPF是项目，BaiduMapControl是百度地图控件，EntityAgent是定义的实体，SimpleMvvmToolkit-WPF是小型Mvvm，为什么没有EF？是因为数据获取是通过WebService的方法获取的坐标信息，因此省略了一些东西，不过这本来就是主要写百度地图API，有没有都无所谓。
地图控件的文件比较多，大体分为：
其中，MapBase文件夹定义的是各种控件基础类，MapLayer文件夹定义的是各种覆盖物基础类，MapService文件夹定义的是各种地图服务的基础类，最后的MapTools文件夹定义的是地图上各种控件基础类，BaiduMap.xaml是百度地图WPF的用户控件UserControl。
MapBase

类MapControl，地图控件，需要注意的是在每个私有方法中，w.InvokeScript("");引号中的方法，是html的js方法，放在api.js文件中。
