considerations regarding the integration of commmand invocations (#1046)

not quite sure how to get the design straight. Also a bit concerned because we'll get this much indirections; the approach to send invocations via the UI-Bus needs to prove its viability

+/** @file command-handler.hpp
+ ** Visitor to process command messages and turn them into command invocations
+ ** in Proc-Layer. Mostly, the UI-Bus is just a star shaped network
+ ** with one central [routing hub][ctrl::Nexus], and serves to distribute
+ ** generic state and update messages. But there are some special messages
+ ** which need central processing: The command preparation and invocation
+ ** messages and the presentation state tracking messages (state marks).
+ ** The Nexus is configured such as to forward these special messages
+ ** to the [CoreService] terminal, which invokes the dedicated services.
+ ** 
+ ** # Lifecycle
+ ** CoreService is a PImpl to manage all the technical parts of actual
+ ** service provision. When it goes down, all services are decommissioned.
+ ** A part of these lifecycle technicalities is to manage the setup of the
+ ** [UI-Bus main hub](\ref ctrl::Nexus), which requires some trickery, since
+ ** both CoreService and Nexus are mutually interdependent from an operational
+ ** perspective, since they exchange messages in both directions.

 <pre>This overarching topic is where the arrangement of our interface components meets considerations about interaction design.
-The interface programming allows us to react on events and trigger behaviour, and it allows us to arrange building blocks within a layout framework. Beyond that, there needs to be some kind of coherency in the way matters are arranged -- this is the realm of conventions and guidelines. Yet in any more than trivial UI application, there is an intermediate level, where things go on, which can not fully be just derived from first principles. It is fine to have a convention to put the &quot;OK&quot; button right -- but how to we get at trimming a clip? if we work with the mouse? or the keyboard? or with a pen? or with a hardware controller we don't even know yet? We could deal with such on a case-by-case base (as the so called reasonable people do) or we could strive at an abstract intermediary space, with the ability to assimilate the practical situation yet to come.

 <pre>A facility within the GUI to// track and manage one specific aspect of interaction state.//
 In a more elaborate UI, as can be expected for such a task like editing, there are interactions beyond &quot;point and shot&quot;. For a fluid and natural interaction it is vital to build and exploit an operation context, so to guide and specify the ongoing operations. Interaction events can not be treated in isolation, but rather in spatial and temporal clusters known as ''gestures''. A good example is the intention to trim or roll an edit. Here the user has some clips in mind, which happen to be located in immediate succession, and the kind of adjustment has to be determined from the way the user approaches the junction point. To deal with such an interaction pattern, we need to track a possible future interpretation of the user's actions as a hypothesis, to be confirmed and executed when all pieces fall into place.

-An InteractionStateManager is a global component, but rarely addressed directly. Rather this tracking component attaches and taps into various information sources to observe some aspects of global state. Moreover, it is outfitted with a set of rules, leading to enablement of some //command invocation trail.// These enablements or disablements are forwarded to the actual trigger points, which are those UI elements to witness the completion of a gesture.</pre>

 <pre>Because we rely on strong decoupling and separation into self contained components, there is not much need for a common quasi-global namespace. Operations needing the cooperation of another subsystem will be delegated or even dispatched, consequently implementation code needs only the service acces points from &quot;direct cooperation partner&quot; subsystems. Hierarchical scopes besides classes are needed only when multiple subsystems share a set of common abstractions. Interface and Implementation use separate namespaces.
