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.

Switch Kryo serialisation to always include the class name, and avoid overhead from writing out SerializedBytes wrapper data.
...
This simplifies the serialisation code, reduces the use of inline functions, and ensures that running SerializedBytes<SuperClass>.deserialise() will correctly return SubClass if that's what it contained, efficiently.

Plumb attachments through to the contract verify functions (no contract uses them yet).

The right way to do this is probably to put the contracts onto the classpath before execution of the contract. However, this interacts closely with the sandboxing work, which isn't yet started, so for now this will do.

Integrate a simple progress tracking system into the protocol framework.
...
The progress tracker API lets you model a tree of steps, along the same structure as protocols and subprotocols. Each step has an (optionally changing) label, and thus progress trackers can be arranged in a tree. Updates to the progress at each level flow up the tree via an RxJava observable (I guess we will use this more in future).
A simple console renderer is provided that uses ANSI escapes and Emoji to show animated progress through a protocol.
The trader demo is enhanced to use this framework, when run outside of Gradle.
