Detailed Description

Publish price feeds for market-issued assets.

Price feed providers use this operation to publish their price feeds for market-issued assets. A price feed is used to tune the market for a particular market-issued asset. For each value in the feed, the median across all committee_member feeds for that asset is calculated and the market for the asset is configured with the median of that value.

The feed in the operation contains three prices: a call price limit, a short price limit, and a settlement price. The call limit price is structured as (collateral asset) / (debt asset) and the short limit price is structured as (asset for sale) / (collateral asset). Note that the asset IDs are opposite to eachother, so if we're publishing a feed for USD, the call limit price will be CORE/USD and the short limit price will be USD/CORE. The settlement price may be flipped either direction, as long as it is a ratio between the market-issued asset and its collateral.
