General progress towards correct array behavior

(Ignore the fact that more tests fail now than before)
* Now have a better understanding of the interconnecting pieces.
* Nesting of containers is now working more and more reliably rather
than just by chance.
* The bit-field array now fails for the same reasons the vector
bit-field array does. This has given insight into the cause of the
errors in general.
* All array processing will soon be resolved.
* This will open the door wide to create the same type of solutions for
the vector.
