During any AA operation in progress, you must not
use Analysis object to start another AA operation
(because it is infinite nesting)
Analysis object may only be used from OUTSIDE
of AA.
To run "suboptimization" use THE ONLY supported
way, i.e. Optimizer API (see optimizer.html file in the ADK subfolder).
