Flambo/develop

Hi,

I got some more functions to be added, together with tests.
Also, I removed dead code (in the current develop-branch at least) and added more output in case of an Exception in the BaseFlamboRegistrator.

However, one change interferes with 5a044dfdf81aa7d0dabe70e5856bc00c8dec29ba, the pull-request from kul/develop: I'm using foreach-partition with an implicit iterator-seq, so usage is easier in the application code. Maybe we could agree on that?

Sincerly,

Chris
