Finished algorithm for generating unknown struct types. User can provide names for fields, or otherwise pyobjus will generate field names for user. User can review generated field names with getMembers function. I tired to use function which accepts generated unknown type, but it work only for pritive types of struct, struct types in struct currently doesn't work, because we aren't made qeuvivalent cython struct, and cast type to that cython type when we are converting python arg to C/Cython arg, so that is causing problems. I don't know how much will be usefull this feature, but in any case is better then nothing, when we return struct of uknown type, and user don't want, or don't know to define required cython struct.
