Document

Appends to the builder the deep comparison of two Object arrays.

1. Check if arrays are the same using ==
2. Check if for null, null is less than non-null
3. Check array length, a short length array is less than a long length array
4. Check array contents element by element using #append(Object,Object,Comparator)

This method will also will be called for the top level of multi-dimensional, ragged, and multi-typed arrays.
