--[[
	A centralized hub for basic metrics reporting.
	This class is designed to provide a baseline exposure to the reporters.

	Context specific Analytics.lua objects should be created in sub-projects,
	to report specific actions like chat interactions, or game page interactions.

	Analytics.lua and the reporters here in Common should serve to cover the
	most common interactions.
