/** @file
* Shell application for Displaying Performance Metrics.
*
* The Dp application reads performance data and presents it in several
* different formats depending upon the needs of the user. Both
* Trace and Measured Profiling information is processed and presented.
*
* Dp uses the "PerformanceLib" to read the measurement records.
* The "TimerLib" provides information about the timer, such as frequency,
* beginning, and ending counter values.
* Measurement records contain identifying information (Handle, Token, Module)
* and start and end time values.
* Dp uses this information to group records in different ways. It also uses
* timer information to calculate elapsed time for each measurement.
