I've been saying for a while[1][2][3] that adding extra abstractions makes
things harder for newcomers, and adding new notations doubly so. And then
I notice this DSL in my own backyard. Makes me feel like a hypocrite.

The implementation of the DSL was also highly hacky:
a) It was happening in the tangle/ tool, but was utterly unrelated to tangling
layers.
b) There were several persnickety constraints on the different kinds of
lines and the specific order they were expected in. I kept finding bugs
where the translator would silently do the wrong thing. Or the error messages
sucked, and readers may be stuck looking at the generated code to figure
out what happened. Fixing error messages would require a lot more code,
which is one of my arguments against DSLs in the first place: they may
be easy to implement, but they're hard to design to go with the grain of
the underlying platform. They require lots of iteration. Is that effort
worth prioritizing in this project?
On the other hand, the DSL did make at least some readers' life easier,
the ones who weren't immediately put off by having to learn a strange syntax.
There were fewer quotes to parse, fewer backslash escapes.
Anyway, since there are also people who dislike having to put up with strange
syntaxes, we'll call that consideration a wash and tear this DSL out.
---
This commit was sheer drudgery. Hopefully it won't need to be redone with
a new DSL because I grow sick of backslashes.

Couple of improvements for the tangle/ directory:
a) Start running tangle unit tests at build time again.
b) Option to print out test names as they run, just like in top-level.

Thanks Max Bernstein for surfacing this idea to my memory.

Fix CI.
In the process I also fixed a bug in the tangle/ utility.

Fix CI. Scenario size_of_shape_shifting_exclusive_container was
triggering undefined behavior in tangle/ and causing things to break in
some compilers but not others.

I'd been toying with this idea for some time now given how large the
repo had been growing. The final straw was noticing that people cloning
the repo were having to wait *5 minutes*! That's not good, particularly
for a project with 'tiny' in its description. After purging .traces/
clone time drops to 7 seconds in my tests.
Major issue: some commits refer to .traces/ but don't really change
anything there. That could get confusing :/
Minor issues:
a) I've linked inside commits on GitHub like a half-dozen times online
or over email. Those links are now liable to eventually break. (I seem
to recall GitHub keeps them around as long as they get used at least
once every 60 days, or something like that.)
b) Numbering of commits is messed up because some commits only had
changes to the .traces/ sub-directory.

Required fixing two levels of bugs:
a) The hack in tangle to drop initial comments a '%' directive..
b) ..was masking a bug where run_mu_scenario wasn't robust to initial
comments.
Mildly concerned that neither of the sub-issues have their own tests,
but I'm just removing hacks, and writing tests for that throwaway
function like run_mu_scenario seems pointless. Instead I've solved the
problem by disallowing comments before '%' directives.
I've also taken this opportunity to at least try to document the
'scenarios' and '%' directives at the first layer where they appear.

I've tried to update the Readme, but there are at least a couple of issues.
