* Renamed RPC JavaHelper functions as RPCDispatcher does not allow more than one method with same name.
Clean up X500 names in Corda simulation, and ensure they're consistent with the standard test names.
This includes using the locations present in those test names, which requires updates to the node
config test.

Move functions for generating transactions into OnLedgerAsset from various locations in
the code (VaultService, AbstractConserveAmount, etc.) to unify the code paths and reduce
duplication.

* Update documentation.
Add CompositeSignature and CompositeSignatureWithKeys classes as part of preliminary work to make CompositeKey signature validation compatible with java.security classes, so that these keys and signatures can be used readily in X.509 certificates.
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.
* Document DemoBench's download link and the location of its log file.
* Document locations of DemoBench's runtime dependencies.

* CORDA-307: Add DemoBench section to the appendix.
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.

Addressed PR comment: removed lockId from WireTransaction.
Fixed soft locking UPDATE statements.
Improvements to VaultSoftLockManager for auto-registration of soft locks for flows with spendable states (as notifications from vault).
Other optimisations (IssuerFlow no longer explicitly reserve/release issued state) and improvements (soft lock release management of soft locks, docs update)
Performance update: now using Requery for UPDATE in release soft locking (non-composite key statement)
Removed redundant TODO messages (TODO: revisit Kryo bug when using THREAD_LOCAL_KYRO)

Improved logging, changed to StateNotAvailableException, using Flow sleep upon retry, tweaked SELECT criteria in coin selection, fixed bug when insufficient states selectable, generateSpend is now @suspendable

Re-introduce selection clause that prevents selection and temporary locking of already locked states (by other flows).
Improved trace logging for coin selection (SQL row level info).
Correctly calling FlowStateMachineImpl sleep (now inlined and working correctly)
Fixed rebase error.
Remove redundant TODO message.
The shell is embedded in the node and offers the ability to monitor
and control the node via the launching terminal.

Additional Unit tests and bug fix for correct spending of multiple contract state types within a single transaction.
Required interface change to states() API to take a setOf (ContractStateClassTypes)
Minor code clean-up.
Re-write NodeVaultService consumed state makeUpdate function using SQL.
* Resolve conflict after rebase from master

Add AnonymousParty superclass of Party in preparation for anonymising parties stored in
contract states.

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.
* Move merkle building extension functions on wire tx to WireTransaction class.
* Add timestamp, notary, transaction type and signers to wire transaction id calculation.
* Change construction of MerkleTree from duplicating last node on a given level to padding leaves' list with zero hash to size of the nearest power of 2 - so we always have a full binary tree.
The problem was that it was possible to construct 2 different transactions with the same ids. Trick worked for txs having number of leaves that were not power of 2.
* Update tear-offs documentation and diagrams to reflect changes in construction of Merkle trees - padding with zero hashes and including all WireTransaction fields in id computation.
* Change in filtering API of WireTransaction for partial Merkle trees calculation.
Instead of many filtering functions over a transaction only one needs to be provided.
Additional change to check and verification of FilteredTransaction.
* IRS demo change. Make filtering function a protected method of RatesFixFlow class.
Comment on situation when capturing too much scope and connected problems with checkpointing.
Change oracle and tear-offs documentation.
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.
