1.项目后端整体迁移至PaddleOCR-NCNN算法，已通过基本的兼容性测试 2.工程改为使用CMake组织，后续为了更好地兼容第三方库，不再提供QMake工程 3.重整权利声明文件，重整代码工程，确保最小化侵权风险 Log: 切换后端至PaddleOCR-NCNN，切换工程为CMake Change-Id: I4d5d2c5d37505a4a24b389b1a4c5d12f17bfa38c

### points to note
|
|
|
|
1. Either of the following combination shall be enough for loading model
|
|
* alexnet.param + alexnet.bin
|
|
* alexnet.param.bin + alexnet.bin
|
|
|
|
2. Never modify Net opt member after loading
|
|
|
|
3. Most loading functions return 0 if success, except loading alexnet.param.bin and alexnet.bin from file memory, which returns the bytes consumed after loading
|
|
* int Net::load_param(const unsigned char*)
|
|
* int Net::load_model(const unsigned char*)
|
|
|
|
4. It is recommended to load model from Android asset directly to avoid copying them to sdcard on Android platform
|
|
|
|
5. The custom IO reader interface can be used to implement on-the-fly model decryption and loading
