Most classes are tightly coupled

This makes it hard to extend the code because most of the sources are tightly coupled. So it is highly recommended to write a class that acts as an "abstraction", helping us access the data and functionalities very quickly and easily.

This will encapsulate the high inter dependence among the classes, and make access and expansion of the library very easy.

I still need to check this out.

This is still an issue. The access should be restricted by making the appropriate fields private. But this can be removed from the milestone.
