def self.parse_description_list reader, match, parent

Returns the Block encapsulating the parsed description list

parent - The parent Block to which this description list belongs
match - The Regexp match for the head of the list
reader - The Reader from which to retrieve the description list

Internal: Parse and construct a description list Block from the current position of the Reader
