Auction Parameters

auctionStart	the block number when the auction was initiated
bondBlock	the block number when a rebalancer successfully submits a bond
auctionMultiplier	a parameter that sets how high the initial auction price is
auctionDecrement	a parameter that sets how quickly the auction price decays

After a bond has been submitted, the required ibRatio after rebalance (newRatio) will be:

a = auctionMultiplier * ibRatio
b = (bondBlock - auctionStart) / auctionDecrement
newRatio = a - b
