Example of a `hostname-style` multicall program

See the documentation for clap::AppSettings::Multicall for rationale.

This example omits the implementation of displaying address config

```bash,ignore
$ hostname
www
```
*Note: without the links setup, we can't demonostrate the multicall behavior*
docs: Re-work examples This creates distinct tutorial examples from complex feature examples (more how-tos). Both sets are getting builder / derive versions (at least the critical ones). 2021-11-30 18:30:19 +00:00			`Jump to [source](multicall_hostname.rs)`

test: More thoroughly test examples This ports our example testing over to [trycmd](https://docs.rs/) so we can: - More thoroughly test our examples - Provide always-up-to-date example usage The old way of testing automatically picked up examples. This new way requires we have a `.md` file that uses the example in some way. Notes: - Moved overall example description to the `.md` file - I added cross-linking between related examples - `14_groups` had a redundant paragraph (twice talked about "one and only one" 2021-11-10 22:15:30 +00:00			Example of a `hostname-style` multicall program
