 * Custom migrations should be defined in this function. This will be called with the CLI 'migrate:v1' command.

 * the migration should be written to run synchronously.
 * @param provider  Web3 provider instance.
 * @param artifactsDir The directory with compiler artifact files.
 * @param txDefaults Default transaction values to use when deploying contracts.
