Detailed Description

Reference implementation of converting between real numbers and values represented by a UniformQuantizedType.

Note that this is not expected to be speedy and may be superseded eventually by a more optimal implementation. Also, the interface assumes that quantization is done per-layer and will need to be wider for various per-channel schemes. As such, this is a placeholder.
