Create format for expressing priority of facts in a bio

I added a bio in 2935384fc1e44119f0e2b338da25e4c1afc9ee2a but I dislike having to maintain lists of things that get out of date and have varying priority. I propose a markup format that enables me to express priority in lists and sentences.

Example:

```xml

Colin Dean is a


software engineer


community builder


non-profit leader


based in


Pittsburgh


Pittsburgh, Pennsylvania


Pittsburgh, Pennsylvania in the United States

.

```

Set `verbosity` of `1` and the output would be

> Colin Dean is a software engineer and community builder based in Pittsburgh.

Set `verbosity` of `2` and the output would be

> Colin Dean is a software engineer and community builder based in Pittsburgh, Pennsylvania.

Set `verbosity` of `10` and the output would be

> Colin Dean is a software engineer, community builder, and non-profit leader based in Pittsburgh, Pennsylvania in the United States.

This enables the user to adjust a slider or choose from options that refine the length of the bio.
