feat(build): remove boilerplate code with lombok

[mbocek]

#85 Example of how to reduce boilerplate code.

[eitch]

I know everyone loves removing boilerplate, but an IDE can easily manage the getters and setters and thus this is just unnecessary dependencies... =) and complicates building etc.

[mbocek]

The build is straight forward. All major IDEs have support for Lombok (IntelliJ Idea, Eclipse...)
As usual, the decision is on the maintainer. For me, less code is better.

@subhra74 Please consider merging this PR as it will be quite helpful later while code cleanup.

[andy-goryachev]

please do not add unnecessary dependencies.
removing boilerplate code is, in my opinion, not the most pressing issue in software development.

@andy-goryachev : I agree, removing boilerplate code is not the most pressing issue.
@eitch : I often see projects having IDE generated getters and setters and equals and hashCode. The issue comes up when someone adds a property later on and doesn't keep all of these in sync. I personally like the lombok approach much better. So I would vote to merge the PR

Lombok doesn't only provide getter/setter but also provide other functionality like logger, builders etc thats why I asked to get it merged.
Anyways its up to the maintainer.
