Implement logging handler for development environment

[MichaelJamesParsons]

Description

Sometimes we use console logs that are useful for debugging in development, but shouldn't be present in production. We should implement a simple wrapper to conditionally log content depending on the environment.

Requirements/Expected Behavior

Implement a logger that outputs messages to the console only in development mode.

debugLogger.info('some useful info');
debugLogger.warn('some useful warning');
debugLogger.error('some useful error');

The implementation should be simple. Something like this will do:

function info (msg) {
    if (isDevMode()) {
        console.log(msg);
    }
}
