	* libmisc/Makefile.am, libmisc/cpuuse/README: Split remaining CPU Usage
	functionality into multiple files to eliminate unnecessary cohesion.
	Update README.
	* libmisc/cpuuse/cpuusagereport.c, libmisc/cpuuse/cpuusagereset.c:
	New files.
	* libmisc/cpuuse/cpuuse.c: Removed.

-This directory contains a CPU usage reported.  It provides two
-primary features:
+This directory contains code to report and reset per-task CPU usage.
+If the BSP supports nanosecond timestamp granularity, this this information
+is very accurate.  Otherwise, it is dependendent on the tick granularity. 
 
-   + provides an educated guess at each task's CPU usage
+It provides two primary features:
+
+  + Generate a CPU Usage Report
+  + Reset CPU Usage Information
 
 NOTES:
 
-1.  CPU usage is "docked" by a clock tick at each context switch.
+1.  If configured for tick granularity, CPU usage is "docked" by a
+    clock tick at each context switch.
+2.  If configured for nanosecond granularity, no work is done at each
+    clock tick.  All bookkeeping is done as part of a context switch.
