Detailed Description

Helper "sentry" class to automatize the safe register/unregister the algorithm's context.

Typical explicit usage:

StatusCode MyAlg::execute()
 {
    IAlgContextSvc* acs = ... ;
    // define the context
    Gaudi::Utils::AlgContext sentry ( this , acs ) ;

    ...

    return StatusCode::SUCCESS ;
 }

Note: for the regular job the context is properly defined with the help of corresponding auditor AlgContextAuditor. This helper class is needed only if one needs to ensure that the algorithm must register its context independently on job/auditor configuration
