What is a handler?

In the scheme of RF24Log naming, a "handler" is simply an object that forwards log message data to one or more output streams.

How to customize handler behavior?

By making each output stream inherit from both RF24LogAbstractHandler and RF24LogAbstractStream, the output stream will inherit the same RF24LogAbstractHandler::log() method that all other handlers use. Additionally, you can wrap the data being forwarded into more complex or custom tailored behavior. We call these wrapped contexts handler extentions. The RF24Log library comes with a sample handler-extention called RF24LogDualHandler located in the "src/handler_ext" folder.
