Feature: Stats

[pepebecker]

It would be nice to have a stats page similar to what Anki has. It would show you a pie chart of for example the following properties: Total, Unseen, Correct, Wrong

I've been trying to add this myself but I'm completely new to Meteor and I'm having a difficult time figuring out how it works.

In the /client/model/vocabulary.js I figured out how to get the total number of words:

new Cursor(() => {}).count();

I tried to get all the failures like this:

new Cursor((entry) => entry[kIndices.failed]).count()

But this only returns the failures of the current 20 cards but not the previous ones

If you have any pointers for me on how I can achieve this, I would be very thankful!
