Add voteScore, fix documentation, make read-only methods virtual

[idolize]

• Addresses issue #5 (vote scores)
• Adds documentation for the .unvote() method (which I did not know exists until I examined the source code)
• Switches the methods which just return a count to be virtual getters
  • Provides a nicer syntax. Ex: comment.upvotes instead of comment.upvotes()
• Updated tests accordingly

Thanks man! This is real awesome stuff!

I'm not sure about the virtuals, but it's not much a concern.

This would be a major release, since the API changes.

Would you give me a couple of days to take a look at it?

I may want to address a few ideas and make a 2in1.

If that's ok to you @idolize, ofc.

No prob! Yeah, I realize the virtual getters would be a breaking change. You could always support both types, but that may be overkill. Personally (and I realize it is personal preference) I vastly prefer the virtual getter way.

Also, at some point it may make sense to actually serialize the "voteScore" to the DB for querying purposes (rather than using a method or virtual property), but that opens a whole new can of worms. If you can figure that out though it'd be awesome!

any updates on this?

Hey @cristiandouce have you had a chance to review this?

[cristiandouce]

@timelf123 not really, no... would you like to?

One idea I wanted to explore is to have some sort of scoreFormatter set by the schema configuration. That way the comment.score or whatever is called would return whatever anyone wants. The default would be a simple upvotes - downvotes... although you can notice the simplicity of this operation...

var score = comment.upvotes.length - comment.downvotes.length;

@cristiandouce will this ever get merged?
