upgrade TiddlyWiki to v2.8.1
...
Notably TiddlyWiki provides now a fallback mechanism
in case the saving to a local file fails due to security
restrictions. When this happens, TiddlyWiki generates a
download link pointing to the current content; this way
one is at least able to "save as" through the browser
context menu.
Due to some controversial policy changes in recent Firefox versions
the support for saving to local files was removed. The rationale
given by the Firefox developers was that this is a rarely used
and generally outdated concept; preferrably people shall use
extensions and save to cloud services (!)
Anyway, Jeremy Ruston, the original author of TiddlyWiki, wrote
a Firefox plugin called "TiddlyFox" to work around these
arcane limitations.

WIP: how to start the actual calculation streams within EngineService
...
this draft fills in the structure how to get from an invocation
of the engine service to the starting of actual CalcStream instances.
Basically the EngineService implementation is repsonsile to
instruct the Segmentation to provide a suitable Dispatcher.

upgrade TiddlyWiki to v2.7.2
...
we were using an very ancient TiddlyWiki version, basically
unaltered since the start of the Lumiera project.
Recent Firefox versions (starting with FF-17) effectively
removed the ability for JavaScript code to get additional
privileges for writing local files; this change seriuosly
undermines the usability of TiddlyWiki and a lot of similar
portable local JavaScript applications.
The original author of TiddlyWiki, Jeremy Ruston, has written
a Firefox plug-in to work around this restriction; this prompts
us to upgrade to a recent TiddlyWiki version as well.
The good news is: recent TiddlyWiki versions are able to import
Tiddlers from older Wikis without much hassle.

brainstorming how to implement the job planning stage
the idea is to built on top of the IterExplorer,

solution idea: again use a builder function?
