Please add a Debug implementation for Graphemes and so on #95
Description
The std::str::Chars iterator has a nice Debug output:
fn main() {
let mut chars = "abc".chars();
println!("{:?}", chars);
chars.next();
println!("{:?}", chars);
}produces:
Chars(['a', 'b', 'c'])
Chars(['b', 'c'])
It would be nice to see unicode_segmentation::Graphemes and so forth implement a nice Debug output to display what they're going to be producing in the future.
