// ErrorSummaryEntry.h - Structure to hold summary of a warning or error
//          message issued in an event.
//
//   Usage:
//  if (edm::FreshErrorsExist()) {
//    std::vector(edm::ErrorSummaryEntry es = edm::LoggedErrorsSummary();
//    package_as_product_in_the_event (es);
//  }
//
//   edm::ErrorSummaryEntry is a very simple struct, containing only strings
//   and an int; it is very suitable for inclusion in the event.
//
//   Unusual C++ practice warning:
//     edm::ErrorSummaryEntry is a simple struct; its members are public and
//     are accessed directly rather than through accessor functions.  Thus it
//     **is reasonable** in this case to treat the code defining the
//     edm::ErrorSummaryEntry as documentation of how to use it.
//
// 20-Aug-2008 mf   Created file.
//
// 22-Jun-2009 mf   Added severity to the structure.  This adds just one
//          integer to the memory used.
