compiles, not really tested.
basic test works 70% of the time, coredumps in the other 30 - but was not easy to debug on a first glance (most interestingly the crash happens in the logging framework - I wonder how that works).
Other tests are not adjusted to the new interface yet.
* change internal reader interface again
* remove some quite embarassing bugs that must have been in the interface for rather long
* add different read methods to script & internal interface (like normal, streaming, etc). Not implemented in ascii reader yet.
But: there are still a few places where I am sure that there are race conditions & memory leaks & I do not really like the current interface & I have to add a few more messages between the front and backend.
But - it works :)
