Command line tool for managing olojs document packages

/**
 *  *stilo init* command
 *  =============================================================================
 *
 *  The *init* command sets up a repository in the current working directory; in
 *  extent, it will create a *.stilo* npm package that will serve as repository
 *  configuration.
 *
 *  ```
 *  stilo init
 *  ```
 *
 *  >   For detailed information about the *.stilo* npm package, see the
 *  >   documentation of the [default .stilo package](../package-template/README.md)
 *
 *  If the current working directory already contains a *.stilo* directory, the
 *  *init* command will quit with a message. In order to re-initialize the repository,
 *  deleting the old *.stilo* package and installing a fresh one, you may use the
 *  *--force* option:
 *
 *  ```
 *  stilo init --force
 *  ```
 *
 *  Finally,
 *  - the `stilo init --help` option will display a help message
 *  - the `stilo init --verbose` option will display a detailed log of the command
