+/** @file proc-dispatcher.cpp
+ ** Implementation details of running commands and the builder.
+ ** The ProcDispatcher is at the heart of the session subsystem and implements
+ ** a (single) session thread to perform commands and trigger builder runs.
+ ** New commands can be enqueued with a dedicated CommandQueue, while the details
+ ** of operation control logic are encapsulated in a [logic component](\ref Looper).
+ ** 
+ ** @todo as of 12/2016, implementation has been drafted and is very much WIP
+ ** @todo                         //////////////////////////////////////////////////////TODO ensure really every state change triggers a wakeup!!!!!!!
+ ** 
+ ** @see ProcDispatcher
+ ** @see DispatcherLooper_test
+ ** @see CommandQueue_test
