### changes
#### remove trailing spaces

When I was using example I noticed trailing spaces.
So, this PR removes the trailing spaces of json file, README, and others.

`examples/with-jest-typescript/src/modules/cars/Overview.tsx` also has it, but this time it did not change as tslint error occurs at commit.

Preferably this installation wouldn't be necessary, but in lieu of a fix...
