Define custom sort order for CSS styles
Deal with misordered styles
Use Private category instead of performSelector:
Make font attribute merging deal with feature array and extract it
Test style parsing
Indentation
Extract +[AshtonUtils CTFontRefWithName:size:boldTrait:italicTrait:features:]
Also use it in AppKit and gracefully handle nonexisting font
If CTFont couldn't be created use system font with requested size
Accept both NSString and NSURL for NSLinkAttributeName
