BaseCameraScanFragment

abstract class BaseCameraScanFragment<T> : Fragment, CameraScan.OnScanResultCallback<T>

相机扫描基类；BaseCameraScanFragment 内部持有CameraScan，便于快速实现扫描识别。

快速实现扫描识别主要有以下几种方式：

1、通过继承 BaseCameraScanActivity或者BaseCameraScanFragment或其子类，可快速实现扫描识别。（适用于大多数场景，自定义布局时需覆写getLayoutId方法）

2、在你项目的Activity或者Fragment中实例化一个BaseCameraScan。（适用于想在扫描界面写交互逻辑，又因为项目架构或其它原因，无法直接或间接继承BaseCameraScanActivity或BaseCameraScanFragment时使用）

3、继承CameraScan自己实现一个，可参照默认实现类BaseCameraScan，其他步骤同方式2。（高级用法，谨慎使用）
