## How it was done

We added the new license header directory by directory, with each commit
covering a single directory to make review easier.
To ensure there are no missing files, we ran the following commands.

```
$ grep -RIL --exclude-dir='.git' --exclude='*.stl' "Apache License, Version 2.0" .
./openarm_bringup/README.md
./openarm_bimanual_moveit_config/README.md
./openarm_bimanual_description/urdf/openarm_bimanual.urdf
./.gitignore
./README.md
./openarm_description/urdf/openarm.urdf
./openarm_description/resource/openarm_description
```

The following files are auto-generated. 
- openarm_bimanual_description/urdf/openarm_bimanual.urdf
- openarm_description/urdf/openarm.urdf
