Limit or Control What gets Input into a redux-form Field using normalizing
Sometimes we need to add a limitation to what the user is inputting into a redux-form Field. For example, in a license plate lookup, we want all the letters to be uppercase regardless of whether the user types them in caps, or when taking a user’s name, we may want the format to be capitalized.
