Truffle/Instrumentation: - Merge instrumentation support into the general execution context; remove separate Instrumentation interface and implementation - Generalize the ?tagging? mechanism for extensibility: the enum PhylumTag is now an interface, and the standard tags moved to the new enum StandardTag - A new ?trap? mechanism interrupts program execution at any probed node holding a specified PhylumTag; this replaces some other special-purpose code. - Refine several interface by factoring out callback methods and simplifying collaboration among key implementation classes.
