 Abstract base that extends `AbstractIItems` and contains the arguments `(layoutRes, ViewHolder lambda, idRes)` in that order. 
 Those variables are used to override the default abstract functions.
 If a layout is only used for one item, it may also be used as the id, which you may leave blank in this case.
-The ViewHolder lambda is typically of the form `{ ViewHolder(it) }`
+The ViewHolder lambda is typically of the form `::ViewHolder`
 Where you will have a nested class `ViewHolder(v: View) : RecyclerView.ViewHolder(v)`
