Using c3-angular with require.js - problem!!

Hello, I am introducing require.js modularisation in my app, which uses c3-angular.

I get an error `c3 is not defined` which puzzles me a lot, because I have specified that c3-angular depends on c3.

Here are a couple of my requirejs shims for c3-angular. Have you got any experience with this sort issues?

```
'c3-angular' : { deps: ['angular','c3'] },
'c3' : { deps: ['d3'], exports: 'c3' },
```

One of the major reasons of trouble in this case is that all c3-angular code is minified.
An uncompressed version would help me enormously with analyzing this problem, and I am opening another issue just for that.
