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