Build all example docs

[saulshanabrook]

If possible, maybe it would be nice to build all example code, to verify that at least it still builds.

I am not sure if there are any tools that make this easier.

@saulshanabrook I actually have a bash script which I run locally to do this, but it should probably be part of the make test process as well.

#!/bin/bash
FILES=($(ls examples/*.go | sed -e 's/examples\///'))

for file in "${FILES[@]}"
do
  echo $file
  go build -o /tmp/$file examples/$file
done
