func (Keeper) GetCurrentValset 

func (k Keeper) GetCurrentValset(ctx sdk.Context) *types.Valset

GetCurrentValset gets powers from the store and normalizes them into an integer percentage with a resolution of uint32 Max meaning a given validators 'gravity power' is computed as Cosmos power / total cosmos power = x / uint32 Max where x is the voting power on the gravity contract. This allows us to only use integer division which produces a known rounding error from truncation equal to the ratio of the validators Cosmos power / total cosmos power ratio, leaving us at uint32 Max - 1 total voting power. This is an acceptable rounding error since floating point may cause consensus problems if different floating point unit implementations are involved.

func (Keeper) GetDelegateKeys 

func (k Keeper) GetDelegateKeys(ctx sdk.Context) []*types.MsgSetOrchestratorAddress

GetDelegateKeys iterates both the EthAddress and Orchestrator address indexes to produce a vector of MsgSetOrchestratorAddress entires containing all the delgate keys for state export / import. This may seem at first glance to be excessively complicated, why not combine the EthAddress and Orchestrator address indexes and simply iterate one thing? The answer is that even though we set the Eth and Orchestrator address in the same place we use them differently we always go from Orchestrator address to Validator address and from validator address to Ethereum address we want to keep looking up the validator address for various reasons, so a direct Orchestrator to Ethereum address mapping will mean having to keep two of the same data around just to provide lookups.

For the time being this will serve
