gist

The idea of these samples to provide an easy to understand example. By means of:
• keep samples as small as possible but still big enough to frame the core idea.
• the data domain is bound to everydays items, no movie/gender/hobby specific.
• code is ready to go, all you need are Java & Maven
• structured in a fancy package tree
• Overall code quality is not a goal. For example - there are lots of duplication. Pieces of code are not reused across the most examples to focus on only one idea per sample.
• No real software examples - to force imagination :-)
