NameParser for Rust

This library is an approximation of my NameParserSharp C# library used to parse peoples' names into constituent parts. For example:

let p = PersonName::parse("Johannes Diderik van der Waals").unwrap();
assert_eq!(p.first, "Johannes");
assert_eq!(p.middle, "Diderik");
assert_eq!(p.last, "van der Waals");
assert_eq!(p.suffix, "");

The original project and therefore my direct C# port are LGPL-encumbered. This implementation is inspired by but not a port of the C#; therefore, I believe it is not LGPL-encumbered. As such, I am releasing this under the MIT license.

This version does not have all the functionality of the other libraries. Notably:

• It only handles parenthetical nicknames such as James (Jimmy) Carter
• The set of prefixes, suffixes, conjunctions, etc., is more limited.
• It doesn't handle parsing out multiple persons from a single input. For example, John D. and Katherine T. MacArthur doesn't parse out to become two individuals.
