	UpgradeName string

	// UpgradeHandlerConstructor defines the function that creates an upgrade handler

Upgrade defines a struct containing necessary fields that a SoftwareUpgradeProposal must have written, in order for the state migration to go smoothly. An upgrade must implement this struct, and then set it in the app.go. The app.go will then define the handler.
