   Tested this out. The grades example now runs on Cloud Dataflow, exercising 
all the float serialization machinery.

> The Go SDK supports all the integer types of the language, but does not 
> support floats.
> My plan for coding is to use the same technique the gob package uses, which 
> results in a compact encoding for simple values.
> [https://golang.org/src/encoding/gob/encode.go?#L210|https://golang.org/src/encoding/gob/encode.go#L210]
>  with rationale explained in 
> https://golang.org/pkg/encoding/gob/#hdr-Encoding_Details
> The resulting uint is then encoded using the existing coders in coderx.
