/* Create A Reducer
 *
 * You need to create a reducer called "appReducer" that accepts two arguments:
 * - First, an array containing information about ice cream 
 * - Second, an object with a 'DELETE_FLAVOR' `type` key
 * (i.e., the object contains information to delete the flavor from the state)
 *
 * The action your reducer will receive will look like this:
 * { type: 'DELETE_FLAVOR', flavor: 'Vanilla' }
 *
