> Currently, we do not pass the outputs of the {{forward}} functions to the {{backward}} functions in the {{nn}} library.  Many of the layers do not need the outputs, but a few current ones, and possible future ones, could benefit from having access to the outputs.  This aims to update the {{backward}} API to include (1) all upstream derivatives, (2) all outputs from {{forward}}, (3) all inputs to {{forward}}.  Effectively, this would be equivalent to having a class object that maintains all configuration and input + output tensors.
> cc [~niketanpansare]  This will require changes to the Barista API, but I believe it will be beneficial for performance.
