OPC-UA Basics

Todo

How much should be in this chapter?

Are we only going to link to external references and skip explaining the OPC-UA basics? The open62541 documentation for example contains a lot of information about how OPC-UA works but in many chapters it also assumes the reader is interested in how the library works. Where do we need to start such that new users can later understand how the concepts of OPC-UA are represented by this library?
