Expression now has to decide how to parallelize
Working so far
More shit
Ugly first, presumably working version.
New mappings
No parallelization if either radix input is empty.
parallelization fix
Fix for dependency management (by JWUST)
Added AsyncConnection from David.
Added new mappings.

    * Original mapping had the totalruntime wrong.
    * It was in fact the runtime of the response task.
Not stopping connection after 30 seconds.

    This allows requests to take longer than the standard timeout of libebb.
