Macro seed::log

macro_rules! log {
    { $($expr:expr),* $(,)? } => { ... };
}

A convenience function for logging to the web browser's console. We use a macro to supplement the log function to allow multiple inputs.

NOTE: log! also accepts entities which don't implement Debug on nightly Rust. It's useful because you don't have to add Debug bound to many places - implementation for logged entity is enough.
