// We don't want to commit built files, so it is useful to have a `clean` script which deletes them if they exist.
// However, Reactochart is built in the root directory
// (so that modules may be required with eg. `require('reactochart/LineChart')`).
// This makes cleanup harder than simply deleting a `build` directory.
// Instead this looks for any files in the root directory which match the name of a file in the `src` directory,
// and deletes them if they exist.
// Sounds dangerous, but any files in root which share a name with src would have been overwritten by the build anyway.
