// ( Vanya Belyaev) patch #1171. The enhancement of existing Algorithm Context Service
//    is the primary goal of the proposed patch. The existing
//    AlgContextSvc is not safe with respect to e.g. Data-On-Demand
//    service or to operations with subalgorithms. The patched service
//    essentially implements the queue of executing algorithms, thus the
//    problems are eliminiated. In addition the enriched interface
//    provides the access to the whole queue of executing algorithms.
