+ * @class CSIPSecChallenge CSIPSecChallenge.h "CSIPSecChallenge.h"
+ *
+ * This class is a base class for challenge, whose inherited classes implement
+ * functionality of algotithm defined in challenge.
+ * Class provides functions for populating common values to credentials
+ * (created from this challenge)
+ * This class also provides functions for resolving type of challenge, realm
+ * and content (SIP authenticate header)
+ *
+ * Inherited class must implement methods:
+ * - Algorithm, which provides digest calculation interface
+ * - VerifyType, that checks the challenge type is correct
