Refactoring

[mpsido]

Big refactoring, changing code structure and merging it with the new features introduced in logDouble branch: #53

[lenzai]

• a lot of changes off topic. Lack of discipline.
• a lot of redundant noise in the diff. This is a bad habbit.
• hiding loadDatabase is questionable, making the behaviour smarter and obscure. Making calls to search database .
• it seems that addSimilarItems is broken. It should embrace the same style as searchDatabase with a callback.

Overall: a lot of noise and distraction , the main change is mostly different, not really better.

[lenzai]

are the changes in app.js part of the fix? Or just a distraction?

Clearly this features is screaming for OOP

Here are the symptoms

• adding global variables
• adding extra arguments to functions.
