WC_CLI_REST_Command() WC 1.0

Main Command for WooCommere CLI.

Since a lot of WC operations can be handled via the REST API, we base our CLI off of Restful to generate commands for each WooCommerce REST API endpoint so most of the logic is shared.

Forked from wp-cli/restful (by Daniel Bachhuber, released under the MIT license https://opensource.org/licenses/MIT). https://github.com/wp-cli/restful
