get_json_object(json_txt, path) - Extract a json object from path 
Extract json object from a json string based on json path specified, and return json string of the extracted json object. It will return null if the input json string is invalid.
A limited version of JSONPath supported:
  $   : Root object
  .   : Child operator
  []  : Subscript operator for array
  *   : Wildcard for []
Syntax not supported that's worth noticing:
  ''  : Zero length string as key
  ..  : Recursive descent
  @   : Current object/element
  ()  : Script expression
  ?() : Filter (script) expression.
  [,] : Union operator
  [start:end:step] : array slice operator
