Improve PLRsearch graphical example
+ Two graphs now. + Larger font in graphs. + More descriptions within graphs. + Text before graphs explaining what is shown. Change-Id: I1da6b55abe7380b61988e03d83f34f7f991085d6 Signed-off-by: Vratko Polak <vrpolak@cisco.com>

+This test case shows quite narrow critical region. Both fitting functions
+give similar estimates, the graph shows the randomness of measurements,
+and a trend. Both fitting functions seem to be somewhat overestimating
+the critical rate. The final estimated interval is too narrow,
+a longer run would report estimates somewhat bellow the current lower bound.
