 """PeaceKeeper benchmark suite.
 
 Peacekeeper measures browser's performance by testing its JavaScript
 functionality. JavaScript is a widely used programming language used in the
 creation of modern websites to provide features such as animation, navigation,
 forms and other common requirements. By measuring a browser's ability to handle
 commonly used JavaScript functions Peacekeeper can evaluate its performance.
 Peacekeeper scores are measured in operations per second or rendered frames per
 second depending on the test. Final Score is computed by calculating geometric
 mean of individual tests scores.
