CoapClient
Provides convenient methods for accessing CoAP resources.
This class provides a fairly high level interface for the majority of

Much finer control of a request can be achieved by direct construction
and manipulation of a CoapRequest itself, however this is more involved,
for most cases the API in this class should suffice. [...]
