 *
 * The Provider class represents one Open Collaboration Service provider.
 * Use the ProviderManager to instantiate a Provider.
 *
 * Accessing functions of the Provider returns a Job class that
 * takes care of accessing the server and parsing the result.
 *
 * Provider files are xml of the form:
