Adding Actions

A new requirement has arisen. As well as being able to raise or lower a column by one, the client wants to be able to set a column to a specific height by entering the height in a text input, like this:

1. What should a "set height" action look like?
2. Will your state object need to change to accommodate this new requirement?
3. Add the <input> and <button> elements to the Column component and check that they appear in the UI.
4. Add an action type, e.g. SET_HEIGHT.
5. Add an action creator for this action.
6. Dispatch an action of this type when the Set button is clicked. Remember to include a height or value in the action to represent the desired height.
