[feature] Tagged logging

[mike-north]

PLEASE MERGE #6 BEFORE THIS

This feature allows prefixes to be pushed onto (and popped off of) a stack, accomplishing something similar to how Rails ActiveSupport/TaggedLogging works

const logger = new Logger();

function fooFunction() {
  logger.pushPrefix('foo');
  ...
  logger.log('hello');
  logger.log('world');
  ...
   logger.popPrefix();
}

logger.log('begin');   // "begin"
fooFunction();         // "[foo]: hello"
                       // "[foo]: world"
logger.log('end');     // "end"

Please review my comments on Prefix styling

[lisaychuang]

Can we eliminate the colons?

[lisaychuang]

What happens if the array is empty and there are no more Prefixes?

[mike-north]

I have confirmed that it will not be harmful, and consistent with what developers expect from [].pop();

You work fast! Thank you for the PR
