59 * This method go through JSON object and finds all CGs to set in a current state.
60 * It also gives each CG it's a unique id. Each id is calculated in a following way:
61 * <li> If CG call is in the root of JSON object it's id will be equals to it's key in JSON
62 * <li> If CG call isn't in a root object it's id will be concatenated keys of
63 * all parent objects + key of CG.
64 * <li> If CG call is in an object that is an element of array CG's id will be
65 * concatenated keys of all parent array + "[i" (where i is a pos of parent object
66 * of CG in array + CG's key)
67 *
68 * This id also used in JSONObject.fillObject() to find CG to use when field that
69 * should be set with CG is found.

71 * @param jsonObject - parsed JSON object
72 * @param CGCreators - hash of factories to create Choice Generators
73 * @return list of choice generators that should be set in a current state.
