// Very fast asynchronous logger (millions of logs per second on an average desktop)
// Uses pre allocated lockfree queue for maximum throughput even under large number of threads.
// Creates a single back thread to pop messages from the queue and log them.
//
// Upon each log write the logger:
// 1. Checks if its log level is enough to log the message
// 2. Push a new copy of the message to a queue (or block the caller until space is available in the queue)
// 3. will throw spdlog_ex upon log exceptions
// Upon destruction, logs all remaining messages in the queue before destructing..
