/**
 * Function used to retrieve an FDC3 Desktop Agent API instance, which
 * supports the discovery of a Desktop Agent Preload (a container-injected
 * API implementation) or a Desktop Agent Proxy (a Browser-based Desktop Agent
 * running in another window or frame). Finally, if no Desktop Agent is found,
 * a failover function may be supplied by app allowing it to start or otherwise
 * connect to a Desktop Agent (e.g. by loading a proprietary adaptor that
 * returns a `DesktopAgent` implementation or by creating a window or iframe of
 * its own that will provide a Desktop Agent Proxy.
 *
 * @param {GetAgentParams} params Optional parameters object, which
 * may include a URL to use for the app's identity, other settings
 * that affect the behavior of the getAgent() function and a `failover`
 * function that should be run if a Desktop Agent is not detected.
 *
 * @returns A promise that resolves to a DesktopAgent implementation or
 * rejects with an error message from the `AgentError` enumeration if unable to
 * return a Desktop Agent implementation.
 *
 * @example
 * const fdc3 = await getAgent();
 *
 * // OR
 *
 * getAgent({
 *     identityUrl: "https://example.com/path?param=appName#example",
 *     channelSelector: false,
 *     intentResolver: false
 * }).then((fdc3) => {
 *     //do FDC3 stuff here
 * };
