View source for REST API:PackageSubscribeClient

The [{{DOCHOST}}/samples/demo/rest/PackageSubscribeClient.java PackageSubscribeClient] demo program extends the [[REST API:BaseClient]] class to subscribe to a package file (a zip file downloaded from the platform). With minor modifications, it can be used to subscribe to a package hosted on the platform.
