H5頁面：我們以WebView的DidFinishLoad事件觸發作為完成加載（Fully Loaded）的時間。

同時對支持performance.timing的設備收集Timing數據，用于詳細分析網絡請求各階段的性能消耗情況。

WebViewDidFinishLoad 官方解釋：Sent after a web view finishes loading a frame.?[Android](http://developer.android.com/reference/android/webkit/WebViewClient.html#onPageFinished(android.webkit.WebView,%20java.lang.String))?[iOS](https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIWebViewDelegate_Protocol/#//apple_ref/occ/intfm/UIWebViewDelegate/webViewDidFinishLoad:)
