The expression manager manages the collection of registered expressions in the workspace. An expression is a snippet of code that can be evaluated to produce a value. Expression creation and evaluation are client responsibilities.
Clients interested in expression change notification may
register with the expression manager - see
IExpressionListener and IExpressionsListener.
This interface is not intended to be implemented by clients.
