Translate the XACML 3.0 policy into Casbin model & policy

[hsluoyz]

We need to finish the code in this repo.

See: https://stackoverflow.com/questions/58460359/converting-xacml-digital-policies-into-caspin-rulesets

Here's how to do it:

1. First read the XACML 3.0 spec: http://docs.oasis-open.org/xacml/3.0/xacml-3.0-core-spec-os-en.html
2. Then play with some XACML code and policy examples. There are a lot of such open-source code of XACML PDP engines like this one: https://github.com/authzforce/core . You can search it on GitHub.
3. Try to map each element of XACML policy into Casbin's model & policy.
4. Implement the translator code in this repo.

@AaqibAhamed I am not an expert in XACML field, I think that XACML is very powerful, we can provide some examples of how to convert <Rule> and <Target> of XACML to Casbin. How do you feel about it?

Hi @hsluoyz , I wanna have a try on this issue.
I think it consists of the following three tasks (plz correct me if I’m wrong):

1. Translate XACML policy into casbin’s model and policy
2. Translate the request file into casbin’s format
3. Verify the correctness of the result given by casbin with response file

@tson1111 yes, please go ahead on it!
