Add Graphing of Caliper Data

### Added via Bower:
- ember-charts
- d3
- Case

### Notes:
- Fixed EAK naming (e.g. not "superheroes_controller.js"; should be "superheroes.js")
- At this point, caliper attributes should probably be extracted to a model, but @romkey that will affect your branch so we can do it there if you want. The anchor with unbound attribute in superheroes.hbs would then become a link-to, which is what it should be.
