Block-Flow: consider usage in ActivityTerm and rectify iteration

Iteration should just yield an Reference to an Extent, thereby hiding all details of the actual raw storage (char[]). This can be achieved by usind a wrapper type around a pointer into the managing vector; from this pointer we may convert into a vector::iterator with the trick described here https://stackoverflow.com/a/37101607/444796 Furthermore, continued planning of the Activity-Language, basically clarified the complete usage scenario for now; seems all implementable right away without further difficulties

+!The Activity Language
+While the Activities are low-level primitives and can be handled directly by the scheduler, any actual rendering invocation must arrange several Activities into a suitable chain of operations. Thus the actual rendering invocation can be seen as a //sentence of the Activity Language.// Formally speaking, it is a //symbolic term.// Not every possible term (and thus sentence) leads to semantically sound behaviour, and thus the ''Scheduler Interface Setup'' is organised in the form of a //builder notation to construct viable Activity terms.// {{{vault::gear::ActivityLang}}} provides the framework for such builder invocations, and allows to create such terms as transient objects -- connected to the durable {{{Activity}}} records allocated into the [[»BlockFlow« memory manager|SchedulerMemory]] backing the Scheduler operation. The language term is thus a front-end, and exposes suitable extension and configuration points for the JobPlanningPipeline to instruct the necessary Scheduler operations to enact a specific [[render Job|RenderJob]].
