func (Keeper) CurrentSignerSet 

func (k Keeper) CurrentSignerSet(ctx sdk.Context) types.EthereumSigners

CurrentSignerSet 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.
