If possible, provide a recipe for reproducing the error.

package main

import (
    "go.opencensus.io/stats/view"
)

func main() {
    meter := view.NewMeter()
    _ = meter.Register()
}

What did you expect to see?

The Register() call to return

What did you see instead?

The meter.Register call hangs forever waiting on the go channel.

I didn't find anything in the documentation that suggested I needed to call Start() before doing any Register calls
