Revamp data card view component as CompositeView

[m4dz]

CardView contains multiples regions, one is the data view. It contains a CollectionView (for datapoints group), each item representing a subset of datapoints (emails, phones, etc). This is counter-productive nor in the Marionette philisophy. Instead, we should set the DataView as a CompositeView which handles the data, and deals with datapoints subset in their collection part. It'll be more simple and performant.
