Feature/refactor

[antony]

I've separated out the core components of the project for readability and understandability.

• A p2p module
• an http server
• The blockchain

and also separated out their individual components.

I've also refactored the code a bit for readability, such as removing nested ifs, and nested functions, and introduced linting in order to spot errors and possible bugs.

I'd probably like to start retrofitting tests if this PR gets approved.

Cheers,
Antony

I actually don't like this approach because the original code is written with a clean Functional Programming approach for learning purposes. If you wanted to improve the previous code you should have embraced the same approach with Higher Order Functions, currying, composing, etc. Putting everything inside classes like a Java code doesn't make it necessarily better.

As I described in more detail in #2 , I intend to leave the main version of naivechain as a single 200 lines of code file.
