/// This file implements the summary view.
///
/// The goal of the summary view is to give a very quick overview of the
/// performance throughput. Below is an example of summary view:
///
///
/// Iterations:        300
/// Instructions:      900
/// Total Cycles:      610
/// Dispatch Width:    2
/// IPC:               1.48
/// Block RThroughput: 2.0
///
/// The summary view collects a few performance numbers. The two main
/// performance indicators are 'Total Cycles' and IPC (Instructions Per Cycle).
///
