Provide use cases for the abstraction

[hulkish]

I suppose this falls under a feature request..

I think there is a lot of great content here. However, honestly they would become far more valuable (to me, at least) if there were use cases detailed in the README.md of each algorithm.

@hulkish If what you're saying is rather than just write out the algos, it will be better to include use cases where each is applicable, you're right.

[hulkish]

@Hoxtygen yea, this is pretty much what I'm getting at. Infact, I think for some of these algo's - because they describe a solution and no problem - folks are prone to mistaking what they should be using.

@hulkish Same frustration I had when learning data structures.
Not sure how the contribution goes, does the provider of the algo have to be the same one to provide use cases or can anyone contribute?

@hulkish this is very good suggestion that you've made. It would be really nice to have the answer on "Why do I need this algorithm and where can I apply it?" question. It may be an "Application" section in each algorithms README file. @Hoxtygen I think anyone may contribute to the algorithms REAMDEs it may not be necessarily the provider of the algo.
