3b1e020082 Extended the data model so that every state has to define a set of 'participants' - parties that are able to consume that state in a valid transaction.
Added protocol for changing the notary for a state, which requires signatures from all participants

ad72f3e48f Add issuer to cash amounts
Add issuer of a cash when referring to amounts of cash (except for the very few cases where
the issuer is not important, such as when referring to aggregated totals across a set of
issuers). Replaces CommonCashState with TokenDefinition, as a more accurate reflection of
what the class represents.

eae3efdf02 Minor: Edit reference after copying amount
Edit reference after copying amount in cash tests, so that when the amount includes
a reference, the copying doesn't replace the changed reference.

f4f0e160d2 Genericise Cash contract to support non-Currency things
Split the verification and commands for the Cash contract into a new AbstractCashLike
class, and make Cash a concrete implementation of that class, specialised for dealing
with Currency as the underlying token.

d7b367965f Genericise Amount class
Make the Amount class generic so it doesn't have to represent a quantity of a
currency, but can handle other things such as assets as well, or extended detail
(for example a currency-issuer tuple).

25e2c4bc4d Add issuance definition for cash contract
Add issuance definition for cash contract, as well as common interfaces to support later
extensions. The issuance definition encapsulates the core values for state objects when
issued, and essentially acts as the Ricardian contract for Corda states.

252eb141a7 Require that a cash Issue command is the only command
Require that a cash Issue command is the only cash command in a transaction.
Although no problems are anticipated with other commands being present, they
could theoretically confuse other verification tools.

fcc36c472a Improve the contracts API and Cash contract a bit, and beef up the unit tests.
Better usage of generics in groupStates so the group exposes the grouping key that was used, this avoids constructs like `val issuer = outputs[0].deposit.party` which is a bit ugly.

cd28733360 Major: Separate out the dep resolution protocol into a couple of sub protocols and use on both sides of the trade.
* Dependency resolution/checking is now working on both sides of the two party trading protocol.
* The commercial paper contract was changed to check timestamping authority identities by name instead of key.
* The trader demo has been rewritten to use the protocol framework, which simplifies the code.

df4d926bca First pass at implementing dependency resolution and checking in the two-party trade protocol.
This commit is incomplete: only the seller side currently checks. The code will be refactored out into subprotocols in further commits.

Note that timeouts are currently unhandled.
