json_value_free and json_object_free

[OpenSourceEverything]

Hello,

It is not clear to me whether a call to json_value_free and json_object_free are both needed when initializing your root value/object pair per example code in the readme.md.

In the example below, is the jason_value_free sufficient to free all memory in addition to the json_free_serialized_string call?

    JSON_Value  *root_value  = json_value_init_object();
    JSON_Object *root_object = json_value_get_object(root_value);
    
    json_object_set_string(root_object, "a","b");

    char *pBuff = json_serialize_to_string_pretty(root_value);
 
    json_free_serialized_string(pBuff);

    json_value_free(root_value);

json_object_free is not part of the API exposed to users. And yes, in the example above, json_value_free and json_free_serialized_string for the string are sufficient.
