mdChip: Implement Chip component with drag, expando, and animations

[ThomasBurleson]

Material Chips are small blocks that represent a complex entity, such as a calendar event or contact. They can contain a photo, short title string (truncated if necessary), and other brief information. Chips are easily manipulated through drag and drop. Touching them invokes the full entity view in a card or full screen view or invokes a menu of options related to that chip’s entity.

Animations invoking and invoked from chips should resize the chip material between entity views for element persistence.

Just as a note, there exists a polymer chip https://github.com/bendavis78/paper-chip

Duplicate of #74? Also, the milestones don't match between the two issues.

@PaulMougel yes this seems like a dupe.

I've written a chips-component, check it out https://github.com/B1naryStudio/md-chips

@BogdanRusinka Its awesome!
but i think you should add keyboard support and make it more "material" when hovering a chip
