Move functions for generating transactions into OnLedgerAsset from various locations in
the code (VaultService, AbstractConserveAmount, etc.) to unify the code paths and reduce
duplication.
Standaridise the identity names of Alice, Bob and Charlie, notary, map service, etc. in order
to ensure consistency across the code base and reduce number of places that have to be changed
to introduce proper X.500 names.
Move Alice, Bob & Charlie identities into the utilities package so they can be used in demos
* Make CompositeKey implement PublicKey
The initial implementation of composite keys as their own distinct class separate from PublicKey
means that the keys cannot be used on standard classes such as Certificate. This work is a beginning
to modifying CompositeKey to being a PublicKey implementation, although significant further work
is required to integrate this properly with the standard Java APIs, especially around verifying
signatures using the new key type.
* First stage of making CompositeKey implement PublicKey interface. Revert to using PublicKey everywhere we expect a key.
* Move algorithm and format into companion object (#432)
Move algorithm and format into companion object so that they can be referenced from other
classes (i.e. the upcoming signature class).
* Add simple invariants to construction of CompositeKey.
Builder emits CompositeKeys in simplified normalised form. Forbid keys with single child node, force ordering on children and forbid duplicates on the same level. It's not full semantical normalisation.
* Make constructor of CompositeKey private, move NodeWeight inside the class.
Add utility function for Kryo deserialization to read list with length constraints.
Add tests for CashIssueFlow, CashPaymentFlow and CashExitFlow. While these were mostly covered by other tests
already, CashExistFlow was not, and any bugs would be harder to identify because they are mixed in with other
functionality (i.e. vault tests)
* Fixed bug whereby Cash Exit was not taking into account the issuer reference.
Added additional JUnit tests for coin selection by issuer.
Added some trace logging in AbstractConserveAmount.
* PR review: added additional state with 3rd issuer reference in test.
Add an AmountTransfer type to express the concept of asset flows.
Unify the currency amount creators and fix a few old style display conversions in teh explorer cash dialogs.
Modifications according to PR comments.
Change TransferAmount display string as it may not always be a payment.

Add AnonymousParty superclass of Party in preparation for anonymising parties stored in
contract states.
Signed-off-by: Ross Nicoll <ross.nicoll@r3.com>
Remove dependency on name data that cash/obligation state objects will not have access to party details (such as name)
once privacy is correctly enforced.
Make FinalityFlow do more, and be used more consistently.
Add a new waitForLedgerCommit API that is intended to be used at the end of flows, or at any other point where a flow wants to wait for a transaction to finalise (but the finalisation flow is being done by someone else).
Update the docs a bit.
Change Party instances to be uniquely identified by the owning key, without taking into account name.
This requires that mock node key generation is reworked so that keys for services and the node itself
are distinct, otherwise the network map service cannot differentiate them.

This deprecates the existing composition clauses and adds new better named versions,
as well as changing 'AnyOf' to require at least one matching subclase (better matching
the name of the clause).
The keys used to sign a command are tested for being a superset of the keys which own
the states, not for being an exact match (as the text previously suggested). This corrects
the message used if this requirement isn't met.

* Update notary change flow to support encumbrances.
Move encumbrance pointer from ContractState to TransactionState.
* Refactor & add new encumbrance tests
