CapTP Ops:
acceptFrom()

NonceLocator <-
acceptFrom(donorPath :String[],
           donorID   :VatID,
           nonce     :Nonce,
           vine      :Vine) :any

VatB picks up the reference to Carol deposited by VatA at nonce in VatC's from-VatA-for-VatB table.

NonceLocator <-
acceptFrom(donorPath :String[],
           donorID   :VatID,
           nonce     :Nonce,
           swissHash :SwissHash),
           vine      :Vine) :any

VatB picks up the reference to Carol deposited by VatA at [nonce, swissHash] in VatC's from-VatA-for-VatB table.

*** Doesn't work until the WormholeOp is implemented. Until then, use the above acceptFrom without the swissHash.
