The intention of this package is to have a context you can pass along methods of your service objects. As functionality and complexity of systems increases you need to provide more and more information from software layer to software layer. Having a context object allows you to put arbitrary data into it and pass one single context along your code flow.
Here we included a logger that can be provided with some context as well. Given
a context the logger marshals all information and print them additionally for
each line. In case you don't care, don't use this logger, or provide nil to
ignore additional payloads.
