  "message": "Expand reporting of timing information.\n\n1. Add an ExecutionSummary object to record execution\n   information about Ceres objects.\n2. Add an EventLogger object to log events in a function call.\n3. Add a ScopedExecutionTimer object to log times in ExecutionSummary.\n4. Instrument ProgramEvaluator and all the linear solvers\n   to report their timing statistics.\n5. Connect the timing statistics to Summary::FullReport.\n6. Add high precision timer on unix systems using\n   gettimeofday() call.\n7. Various minor clean ups all around.\n\nChange-Id: I5e09804b730b09535484124be7dbc1c58eccd1d4\n",
