ns-3 stats example

The example script wifi-example-db.sh in this directly will run

through the entire process of running a simple experiment.  It assumes

sqlite3 is installed as it uses the sqlite3 data output format of the

statistics package.  It also assumes it is being run from the

examples/stats/ subdirectory of the ns-3 package, together with its

gnuplot script.  When the script completes successfully, a graph will

be have been produced in examples/stats/wifi-default.eps demonstrating

output from this example.

More information on the statistics package and this example is

available online on the ns-3 wiki at:
