Overview

Adds support for the `timers` module to browserify.

# Wait, isn't it already supported in the browser?

The public methods of the `timers` module are:

- `setTimeout(callback, delay, [arg], [...])`
- `clearTimeout(timeoutId)`
- `setInterval(callback, delay, [arg], [...])`
- `clearInterval(intervalId)`

and indeed, browsers support these already.

# So, why does this exist?

The `timers` module also includes some private methods used in other built-in Node.js modules:

- `enroll(item, delay)`
- `unenroll(item)`
- `active(item)`

These are used to efficiently support a large quantity of timers with the same timeouts by creating only a few timers under the covers.

Node.js also offers the `immediate` APIs, which aren't yet available cross-browser, so we polyfill those:

- `setImmediate(callback, [arg], [...])`
- `clearImmediate(immediateId)`

# I need lots of timers and want to use linked list timers as Node.js does.

Linked lists are efficient when you have thousands (millions?) of timers with the same delay. Take a look at timers-browserify-full in this case.
