Gatling

Run default example:

$ ./gatling/bin/gatling.sh -sf gatling/user-files/simulations/computerdatabase/ -s computerdatabase.BasicSimulation -m

For a minimal setup using https://gatling.io/docs/current/extensions/maven_plugin/, then one can run it using mvn gatling:test.

For using io.gatling.highcharts:gatling-highcharts-maven-archetype, it seems have problem to run inside of Eclipse (I can't "add scala nature" even if I follow this toturial. However, to make it working in IntelliJ IDEA is quite straightforward (add scala plugin is kind of the only thing which need to handle).
