XMLRPC client library.
see if we can make better use of interfaces
add a separate function for multicall? where we turn the responses into Fault’s if they are so
make it work when we write an to a int (maybe in a struct). now it complains it should be an int64.
make xmlrpc tags works for writing out structs too
document how encoding & decoding is done, including struct tags for xmlrpc.
work with charsets other than utf-8?
properly do decoding when more specific types are passed in
more test cases, also for invalid xml
test with more explicit types passed in
test if decoding into arrays work (as opposed to slices)
