* [Chips] Chip component * Update description * Readme fixes * NSMutableArray -> NSArray * Use MDCSlider * Chips examples CBC * MDCChipCollectionViewCell.m * Sanitize example * Left align single-item rows * Copy * Check mark * Use static inline instead of #define * initWithFrame:CGRectZero * encoding decoding * GGRectGetMinX * If no title color has been set for a given state... * Use new icons * rm init override * alwaysAnimateCellResize -> alwaysAnimateResize * MDCChipCollectionViewCell initWithCoder * Fix MDCChipView encoding * Fix indent * Fix sizing images * Use UIEdgeInsetsInsetRect * Layout around hidden accessory view * TODO Pull background color from MDCPalette * Add The chip uses this property to determine intrinsicContentSize and sizeThatFits. * Use static functions instead of UIColor extension * sizeToFit -> setNeedsLayout
