Object mapping

In order for frontend and backend to communicate, we use some form of common language (mostly JSON). In our case, we will be using JSON for communication between backend when some action is performed from the frontend (using JavaScript-jQuery). We convert the JSON to objects, which are understood by our backend, using an object mapping library. In this, we will be using the popular Jackson library for object mapping.

We are going to add an additional dependency for object mapping of the PostGIS data-structures.
