Loading custom operator as an external module helps creating new operator without re-compiling mxnet from src. Tensorflow and PyTorch also provide such function.

1. Install mxnet from src, you may refer to script.
2. git clone https://github.com/DuinoDu/load_op.mxnet
3. cd load_op.mxnet
4. set mxnet root path in Makefile
5. make
