Add a reference to the graph for a node in a graph
Add debugging stuff to ufo-daemon
Add profiler for network messaging
Extend ufo-profiler
cleanly disconnect the ufo-daemon
Don't write messenger profiling events empty
Add message to get remote number of CPUs
Add --lo-local option to disable local GPU computation

* Can also be set in python via no-local property on UfoConfig
Refactor messager handling into own function
Add function to replace a node in a graph
(ugly) Have writer task on (last) remote node over network
Don't rely on addresses to determine the writer node
Only dump .dot file in debug mode
Cleanup
Fix wrong initialization of message size
Print what mpicc is used

* In cluster installations, often several MPI implementation
  are present, and using a different mpirun that does not match
  the used mpicc will result in cryptic error message. Always
  make sure that you use the right mpicc!
Add cmdline flag --network-writer / -w

* Will make the LAST remote node (specified on the cmdline on zmq, or having highest rank on MPI) a dedicated writer node
* The writer node will not do any computations
Dump received task graph in debug mode
More debug output
Fix unitialized data frame causing SEGFAULT
