--[[
	Exposes an interface to set global configuration values for Roact.

	Configuration can only occur once, and should only be done by an application
	using Roact, not a library.

	Any keys that aren't recognized will cause errors. Configuration is only
	intended for configuring Roact itself, not extensions or libraries.

	Configuration is expected to be set immediately after loading Roact. Setting
	configuration values after an application starts may produce unpredictable
	behavior.
