I have a question about this, that I had since the original coffee version.
Why are you using 'this' to store the collections? I had never seen the use of 'this' in this context in Meteor.
Afaik, the normal way to do it is to use a global variable, something like:

```
Cento = {}
Cento.Solutions = ....
```

etc.

It doesn't look like using 'this' is causing any problem, but I was curious of why you chose to do it that way.
