carefully move files from root into src

**Is your feature request related to a problem? Please describe.**
Right now we have only 2 files, related to code at our root folder. i think it's time to move them out too. so at root we'll have only folders and configuration files.

**Describe the solution you'd like**
files, that we need to move:
- https://github.com/GroceriStar/sd/blob/master/files.js
- https://github.com/GroceriStar/sd/blob/master/filesObjects.js

**Describe alternatives you've considered**
But be careful, because we'll need to update paths, inside `files.js`
actually, if you'll create a variable, that have a same filepath to ```data``` folder - you'll increase quality of this file....

Note: please be aware, that maybe after moving this files we'll break some of functionality. so maybe use Ctrl+F or check our files manually and update imports accordingly.
