   - [x] Changes are complete (i.e. I finished coding on this PR)
   - [ ] All changes have test coverage: N/A
   - [x] Code is well-documented: 
   - [x] To the my best knowledge, examples are either not affected by this 
change, or have been fixed to be compatible with this change
   
   ### Changes ###
   - Modified example/ctc to include both sym.contrib.ctc_loss and sym.WarpCTC 
loss in one example
   - Added multiprocess CAPTCHA image generation to allow fast training
   - Reorganized the code into different files
   - Added code for inference by loading symbol and parameters from checkpoint
   - Removed predict_ocr.py script because:
     - It is broken, even after fixing the amalgamation library
     - Python interface of amalgamation library has dependency on mxnet.so, 
which defeats the purpose of using amalgamation
   - Updated README
   - Updated the associated tutorial
   - Removed speech_lstm tutorial since the associated example is already 
removed
