[elyses-enchantments] Concept exercise

[colinleach]

Pairs with the vectors concept.

Content is mostly new, ported from what I previously did for R. The earlier draft in exercises/concept.wip is removed to avoid conflicts.

Working towards getting a root and a trunk for the start of the syllabus, I think this is where it's at:

Concept	Status	Exercise	Status
basics	#779	lasagna	#780
booleans	merged	annelyns-infiltration	merged
numbers	merged	currency-exchange	#808
conditionals	#799	cars-assemble	#832
vectors	#802	elyses-enchantmants	#833

Of course, there is also a lot of stuff lower down that's making good progress. However, getting to see the start of a coherent syllabus on the Exercism website is becoming a priority for me (you may hear that old people learn patience, but only up to a point).

There appears to be some discrepancy with the naming of some files. Should it be "enchantmants" or "enchantments"? I'm not sure if this was done with some purpose to avoid the old name or not.

Otherwise, there are a couple of small typos in design.md, introduction.md and elyses-enchantmants.jl, which I'll just edit directly.

That was 100% unintended screwup, where my fingers bypassed my brain. It should always be "enchantments".

In case you wondered how I managed to get it wrong in so many different places: I used a Bash script to generate the exercise structure, so once I made a typo on the command line it propagated widely.

Also, it's been a bad few days for config.json issues. I suspect we've not seen the last example of that.

We got there in the end...

I think this is the current top-of-syllabus progress:

Concept	Status	Exercise	Status
basics	#779	lasagna	merged
booleans	merged	annalyns-infiltration	merged
numbers	merged	currency-exchange	#808
conditionals	merged	cars-assemble	merged
vectors	merged	elyses-enchantmants	merged
ranges	draft #803	chessboard	#835
vector-operations	draft #819	bird-watcher	wip

That gives us 3 boxes on Exercism, with 3 more well advanced.

I'm partway through implementing bird-watcher (I decided I prefer this to elyses-analytic-enchantments).

I also found my 80%-complete draft of the strings concept, which will be another important node on the syllabus. Now I just need to figure out what I was intending to write, before I got ill.

Looking good! I'll try to keep reviewing, so we can keep moving forward.
