> In a scenario where there are many files which all share the same key/value 
> types, e.g., when dealing with measured data from sensors, it should be 
> possible to chain-load multiple files. That means, there should be a reader 
> which can be supplied with one or more directories containing files, and it 
> should be possible to read the records of all files in order.
