Android Dalvik VM executable (dex): Go parsing library

Android OS applications executables are typically stored in its own format, optimized for more efficient execution in Dalvik virtual machine.

This format is loosely similar to Java .class file format and generally holds the similar set of data: i.e. classes, methods, fields, annotations, etc.
