// * Entry: information about execution of a single perf test. This corresponds to one line in CSV file.
// * Batch: a group of entries that were created together during a single execution. A new batch is created each time
// one or more perf tests are executed. All entries in a single batch will have a matching ImGuiPerflogEntry::Timestamp.
// * Build: A group of batches that have matching BuildType, OS, Cpu, Compiler, GitBranchName.
// * Baseline: A batch that we are comparing against. Baselines are identified by batch timestamp and build id.
