SSRS renderingCompleted delegate

Comment from: \Classes\SrsReportRunController\renderingCompleted

/// Write event handlers and hook into this to handle the rendering complete event.
/// IMPORTANT NOTE: Please ensure you register your event handler in <c>preRunModifyContract</c> method.
/// This will ensure that event is called in both batch and interactive scenario.
/// For interactive cases controller <c>main</c> method is called. For batch case controller <c>run</c> method is called.
/// Both batch and interactive call <c>preRunModifyContract</c> prior to running report.
/// If using <c>SrsPrintMgmtController</c> you can also register this event in <c>runPrintMgmt</c> method.
