Restructured pom to add samples project

@christiangoudreau 
Is that how you wanted to add a samples project?

I also reformated the code so it's 4 spaces everywhere.
If any styling changes are needed, I suggest I do them in this PR so the whole project will be uniform.

What I see is that jukito use "one empty line at beginning of class"
