-   * Convert a standard URL encoded form input into a parsed JSON tree.
-   *
-   * <p>Given an input such as:
-   *
-   * <pre>
-   * message=Does+not+compile.&labels.Verified=-1
-   * </pre>
-   *
-   * which is easily created using the curl command line tool:
-   *
-   * <pre>
-   * curl --data 'message=Does not compile.' --data labels.Verified=-1
-   * </pre>
-   *
-   * converts to a JSON object structure that is normally expected:
-   *
-   * <pre>
-   * {
-   *   "message": "Does not compile.",
-   *   "labels": {
-   *     "Verified": "-1"
-   *   }
-   * }
-   * </pre>
-   *
-   * This input can then be further processed into the Java input type expected by a view using
-   * Gson. Here we rely on Gson to perform implicit conversion of a string {@code "-1"} to a number
-   * type when the Java input type expects a number.
-   *
-   * <p>Conversion assumes any field name that does not contain {@code "."} will be a property of
-   * the top level input object. Any field with a dot will use the first segment as the top level
-   * property name naming an object, and the rest of the field name as a property in the nested
-   * object.
-   *
-   * @param req request to parse form input from and create JSON tree.
-   * @return the converted JSON object tree.
-   * @throws BadRequestException the request cannot be cast, as there are conflicting definitions
-   *     for a nested object.
