i cannot find a version anywhere. i don't know if it really buys us anything though.as for library, well, it's not really 'appsdk' is it? the calling code is in app-catalog, so then do we put 'app-catalog'. I just don' know. I think the 'name' gives us what we want.  If you have a strong feeling on the library, add 'library' to this.headers ={ and it will take affect.
