Replace JAXB with AB1 Storage code

[yamidark]

Depends on #383

We are trying to ensure Java 9 compatibility for the project.

However, the project uses java.xml.bind module, which is marked as
deprecated in Java 9.

As discussed here, using deprecated modules is bad practice, thus we should switch to another method for storage purposes.

As discussed here, let's reuse the AB1 storage code for the AB2 project.
