Simon Michael adb6ee40eb lib: clarify price types (#131)
dropped journalPrices

renamed Price to AmountPrice,  AKA "transaction price"

renamed MarketPrice to PriceDirective.

added new MarketPrice (more pure form of PriceDirective without the amount style information)

Prices is now a more efficient data structure, but not used yet.
