[chrisreddington]

Definition of done:

• World Event Engine Deployed
• World Event Engine Tick Triggered
• Update naming conventions for consistency
• Investigate invoke method
• Refactor for re-usability / additional events (enabling below scenarios)
• Random event selected (Only 1 event available so far, this one!)
• Random parameters selected (e.g. from a range of X to Y, each BarType is impacted in a different way - e.g. -0.5 to 0.5 multiplier)
