Console logging backend

This is a logging implementation for log that is designed for console programs. It is easy to configure, optionally integrates with structopt for configuration, and can write log messages to stderr in concert with indicatif for coordinated logging and progress reporting.

Example

You can use this as follows:

use log::*;
use happylog::*;

fn main() -> () {
    initialize(0).unwrap();
    info!("info logging message");
}

Major Changes

In 0.3, Happylog changed to use Fern instead of its own log target. It will eventually expose Fern dispatchers to allow for more thorough log configuration.

It also no longer requires log guard objects; it maintains an internal MultiProgress and allows progress bars to be added to them. Code using happylog should usually not use MultiProgress directly.
