	OwnerAddress string       `json:"owner_address"` // Sender of BondTx - UnbondTx returns here
	Shares       string       `json:"shares"`        // Total number of delegated shares to this candidate, equivalent to coins held in bond account
	VotingPower  int64        `json:"voting_power"`  // Voting power if pubKey is a considered a validator

}

Candidate defines the total Amount of bond shares and their exchange rate to coins. Accumulation of interest is modelled as an in increase in the exchange rate, and slashing as a decrease. When coins are delegated to this candidate, the candidate is credited with a DelegatorBond whose number of bond shares is based on the Amount of coins delegated divided by the current exchange rate. Voting power can be calculated as total bonds multiplied by exchange rate. NOTE if the Owner.Empty() == true then this is a candidate who has revoked candidacy
