[Contribution] Script for making the necessary files for a new model

[Sahandfer]

I've made a script for making the necessary files for a new model that:

1. Make a model file in cogdl/models/nn/
2. Make an example file in examples
3. Add to tests/tasks/ file
4. Add to match.yml
5. Remind the user to add their model to README.md

The script can be tested by

$ python scripts/model_maker.py

@cenyk1230 Hello, the issues raised by Travis are not from parts I added. Am I expected to fix them for my pull request to be accepted? Let me know if that's the case. Thank you

Hi @Sahandfer, I have fixed the issues with the code in the master. Please wait for the re-run.

@Sahandfer Nice job. But I wonder whether the template model should be also tested.

[Sahandfer]

Thank you @cenyk1230! I think the template files I created serve as an interface for new models to be added; since they don't have any logic or calculations within them, I don't see it as necessary to test them. However, one improvement that I can think of is modifying the templates in the future after establishing a global style for cogdl models.

Hi @Sahandfer, I think maybe the template files can be moved to a new folder such as template/ (maybe template/nn/) in the root directory since each file in the cogdl/ will be used for computing coverage.

[Sahandfer]

Hello @cenyk1230, I think that's a great suggestion. I have moved the two templates to a new template folder and they are now called: base_model and base_example. I have also updated the script to use these templates.

[cenyk1230]

@Sahandfer It seems that you moved the wrong model file. I think you should git mv the cogdl/models/nn/template.py rather than cogdl/models/base_model.py.

@cenyk1230 Sorry for that. I fixed my mistake; however, the coverage has decreased but I'm not sure what the reason for that is. Thank you and sorry for the trouble.

Well done!
