Logger class that allows specifying which log levels would be logged to the console.
(e.g., turning on Debug level would print all messages useful for debugging)
Since console.* calls are synchronous, logging happens only in a development environment (when React Native packager is running)
to ensure it doesn’t degrade the performance of a released application.
