/**
 * Perform authentication.
 *
 * Params:
 * 	- realm (string): The name of the realm. (Default: "web")
 * 	- datasource (string): The name of the datasource that should be used to authenticate.
 * 	  This datasource must be an `auth.UserDatasource`. (Default: "auth.UserDatasource")
 *
 * Context:
 * 	- http.Request (*http.Request): The HTTP request. This is usually placed into the
 * 	context for you.
 * 	- http.ResponseWriter (http.ResponseWriter): The response. This is usually placed
 * 	 into the context for you.
 *
 * Datasource:
 * 	- An auth.UserDatasource. By default, this will look for a datasource named
 * 	  "auth.UserDatasource". This can be overridden by the `datasource` param.
 *
 * Returns:
 * 	- True if the user authenticated. If not, this will send a 401 and then stop
 * 	  the current chain.
