-%% An example Diameter client that can sends base protocol RAR
-%% requests to a connected peer.
-%%
-%% The simplest usage is as follows this to connect to a server
-%% listening on the default port on the local host, assuming diameter
-%% is already started (eg. diameter:start()).
-%%
-%% client:start().
-%% client:connect(tcp).
-%% client:call().
-%%
-%% The first call starts the a service with the default name of
-%% ?MODULE, the second defines a connecting transport that results in
-%% a connection to the peer (if it's listening), the third sends it a
-%% RAR and returns the answer.
