update the look of components structure.

# 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.
