update the look of components structure.

[atherdon]

Description/Steps to reproduce

I like that each component has a separated folder. It's cool
I don't like: index.js should be replaced with component name.
example:

/Directions/
  index.js -> Directions.js

And test.js should be replaced too. example:

/Directions/
   test.js -> Directions/Directions.test.js 

This is how Jest will know how to parse that tests

For now i'm ok with style.js file, later, when the project will be more complex - we'll address that.

Expected result
