public interface HCodeElement

HCodeElement is an interface that all views of a particular method's executable instructions should implement.

HCodeElements are "components" of an HCode. The correspond roughly to "an instruction" in the HCode "list of instructions". Each HCodeElement should be traceable to an original source file and line number, and possess a unique numeric identifier.
