/**
 * A client instance provides the main API surface to interact with a network of
 * peers and orderers. An application using the SDK may need to interact with
 * multiple networks, each through a separate instance of the Client.
 * <br><br>
 * An important aspect of the current design of the Client class is that it is <b>stateful</b>.
 * An instance must be configured with a <code>userContext</code> before it can be used to talk to the fabric
 * backend. A userContext is an instance of the {@link User} class, which encapsulates the ability to sign
