Truffle/Instrumentation: significant rearrangement (including moved class) and extension of the Truffle Instrumentation Framework. New interfaces include DebugContext (which can be attached to the ExecutionContext), through which access is provided to possibly language-specific (a) node instrumentation, (b) debug services manager, (c) notification when programs halt, (d) display of language values, and (e) display of variable identifiers.
