subclass state objects.

FungibleAssets and Cash
-----------------------
There is a common ``FungibleAsset`` superclass for contracts which model fungible assets, with ``Cash`` being the obvious
example. This is intended to be readily extensible to cover other assets, for example commodities could be modelled by
using a state object that included further details such as location of the commodity.
There is a common ``FungibleAsset`` superclass for contracts which model fungible assets, which also provides a standard
interface for its subclasses' state objects to implement. The clear use-case is ``Cash``, however ``FungibleAsset`` is
intended to be readily extensible to cover other assets, for example commodities could be modelled by using a subclass
whose state objects include further details (location of the commodity, origin, grade, etc.) as needed.
