Determine if a char is a valid identifier for a parser and/or lexer according to Unicode Standard Annex #31 rules.

Documentation

```rust extern crate unicode_xid;

use unicode_xid::UnicodeXID;

fn main() { let ch = 'a'; println!("Is {} a valid start of an identifier? {}", ch, UnicodeXID::isxidstart(ch)); } ```

features
