[jonasgrunert]

Changed Input to be a class to bea ble to access refs
Corresponding to issue #92

Checking back for the build errors tomorrow. Seems like the version of the types did change and broke some specifications.

After some investigation I found the simple cause of my problem.
On the other hand yarn, has multiple problems setting up the project due to incorrect versioning. Maybe someone can look into that later on.

Coverage remained the same at 100.0% when pulling ff7da4f on jonasgrunert:master into 0ab9c67 on AlgusDark:master.

Unintenional side effects occur. I will close this for now and add a proper solution this weekend

+1 thanks for working on it. Would like to add a simple ref to focus an input in componentDidMount()
