 Options for #tag
 
 * :as (symbol) -> use this as the html element ([b] becomes strong)
 * :match (regex) -> convert this tag and its content to html only if the content matches the regex
 * :parents ([symbol]) -> ignore this tag if there is no open tag that matches its parents
+* :singular (true|false) -> use this if the tag does not require an ending tag
 
 
 When you pass a block to #tag it is expecting you to return a string.  You have two variables available to your block:
 
 * meta -> Everything after the '=' in the opening tag (with [quote="Legendary"] meta returns '"Legendary"' and with [quote] meta returns nil)
 * content -> Everything between the two tags (with [b]strong arm[/b] content returns 'strong arm')
+* singular? -> Tells you if this tag is being parsed in singular form or if it had an ending tag (affects if content has any data)
