## Quick Start
```rust
use rall::{SimpleLogger, Level};
For the fastest setup possible, declarative macros are exposed that have a predefined format.
This is to allow hassle-free and painless setup that will let you log instantly!
// Create Default SimpleLogger
let mut logger = SimpleLogger::default();
```rust
use rall::{debug, error, fatal, info, trace, warn};
// Log Out To Standard Output
logger.log(Level::TRACE, "My Best Friend Hazel :D");
logger.log(Level::DEBUG, "My Best Friend Hazel :D");
logger.log(Level::INFO, "My Best Friend Hazel :D");
logger.log(Level::WARN, "My Best Friend Hazel :D");
