Example output when shading asm and accessors-smart into the same assembly. After the changes were applied the overlapping classes error was resolved.

  - org.objectweb.asm.Type
  - org.objectweb.asm.AnnotationVisitor
  - org.objectweb.asm.MethodVisitor
  - org.objectweb.asm.Attribute
  - org.objectweb.asm.MethodWriter
  - org.objectweb.asm.Handler
  - org.objectweb.asm.ByteVector
  - org.objectweb.asm.Opcodes
  - org.objectweb.asm.signature.SignatureReader
  - org.objectweb.asm.FieldVisitor
  - 15 more...

Waiting for this as well.

I think it would be fair to assume that this project is dead/unmaintained.

The last commit was Nov 2015... which is 13 months ago.

This PR was merged only 2 months ago, so it isn't as dead as claimed.

@UrielCh Would you be able to cut a release with these changes?
