[Subtree] Removing import-layers directory
As part of the move to subtrees, need to bring all the import layers content to the top level. Change-Id: I4a163d10898cbc6e11c27f776f60e1a470049d8f Signed-off-by: Dave Cobbley <david.j.cobbley@linux.intel.com> Signed-off-by: Brad Bishop <bradleyb@fuzziesquirrel.com>

+ PYBOOTCHARTGUI
+ ----------------
+
+pybootchartgui is a tool (now included as part of bootchart2) for
+visualization and analysis of the GNU/Linux boot process. It renders
+the output of the boot-logger tool bootchart (see
+http://www.bootchart.org/) to either the screen or files of various
+formats. Bootchart collects information about the processes, their
+dependencies, and resource consumption during boot of a GNU/Linux
+system. The pybootchartgui tools visualizes the process tree and
+overall resource utilization.
+
+pybootchartgui is a port of the visualization part of bootchart from
+Java to Python and Cairo.
+
+Adapted from the bootchart-documentation:
+
+ The CPU and disk statistics are used to render stacked area and line
+ charts. The process information is used to create a Gantt chart
+ showing process dependency, states and CPU usage.
+
+ A typical boot sequence consists of several hundred processes. Since
+ it is difficult to visualize such amount of data in a comprehensible
+ way, tree pruning is utilized. Idle background processes and
+ short-lived processes are removed. Similar processes running in
+ parallel are also merged together.
+
+ Finally, the performance and dependency charts are rendered as a
+ single image to either the screen or in PNG, PDF or SVG format.
