Detailed Description

Utility class that carries the DWARF compile/type unit and the debug info entry in an object.

When accessing information from a debug info entry we always need to DWARF compile/type unit in order to extract the info correctly as some information is relative to the compile/type unit. Prior to this class the DWARFUnit and the DWARFDebugInfoEntry was passed around separately and there was the possibility for error if the wrong DWARFUnit was used to extract a unit relative offset. This class helps to ensure that this doesn't happen and also simplifies the attribute extraction calls by not having to specify the DWARFUnit for each call.
