Advanced (and sometimes experi/\/\ental)

feature description example output
@key generates a nested JSON dataset rows=1&name={firstName}&@friends={rows=5} [{"name":"Sheldon","friends":[{},{},{},{}]}]
subset configuration requires * (asterisk) as a parameter delimiter rows=1&name={firstName}&@friends={rows=5*name={firstName}} [{"name":"Kendall","friends":[{"name":"David"},{"name":"Joann"},{"name":"Jerrod"},{"name":"Theresia"},{"name":"Leela"}]}]
Cannot currently render more than one level of nested data.
WILL NOT WORK: ?rows=1&fname={firstName}&@friends={rows=1*friendName={firstName}*@nestedFriends={rows=5}}
?gist generates JSON from a gist ?gist=2260cda3c59f6df8edef awesomesauce.
