This is a work in progress.

The goal is to enable light-weight operations on values with units attached to them, including implicit unit conversion.

For instance, the following should be possible:

```go

mps := si.Meter.Div(si.Second)

speed := mps(5)  // 5 m/s

dist := speed.Mul(si.FromDuration(5*time.Second))

fmt.Println(dist)  // "25 m"

mph := us.Mile.Div(us.Hour)

speed = speed.Convert(mph) // now "11.185 mi/hr"

fmt.Println(dist.Div(speed))  // "5 s"

```

Stretch goal is compatibility with GNU Units `definitions.units`, something like:

```go

defs := unitdef.Definitions()  // read and parse definitions.units

mps = defs.Must("m/s")

dist := mps(5).Mul(si.Second(5))

fmt.Println(dist)  // "25 m"

```
