Initial Tensor => Tensor predictions based on frozen models

Scala model that can be created by frozen model.

Prediction method that takes in Input tensor and produces correct Output tensor.

Unit tests that test this over a variety of models, normalizations, tasks, etc.

The issue names no files, tests, or entry points. Start by locating the Scala model and frozen-model interfaces, then determine how input and output tensors are represented. Done means a model can produce predictions from input tensors and unit tests cover varied models, normalizations, and tasks.

Written by the indexing model from the issue text.
