These graphs help us map policies that are inherited from the parent and also lateral policies that are assigned to the users given that the user has a particular permission. Currently, the hierarchy has been defined for org & application. Need to cascade it to more documents such as pages & actions.
We are moving to a multi-module structure so that different parts of the codebase can be exposed to the public while others can remain private. Using pf4j for plugin framework.
Also adding a build script `build.sh` which compiles the code and creates the `dist` folder for distribution purposes. Now we can build the code via
```
$ ./build.sh -DskipTests
```
