Fixing 'Example Code'

[Wesley-Arrington]

• Made 'Example Code' a consistent size throughout document
• Added in 'Example Code' on several pages
• Added in missing programming language titles

I checked the changes in this PR for correctness and I can say there are no errors in it. I'd still like to pull @leios into this PR to discuss which size headline we want to use for "Example Code". In my opinion, it should be a H2 (##) because it should be one level lower than the chapter headline, which is a H1 (#) since the example code is part of the chapter and not a chapter in itself.

[leios]

Yeah, agreed. If we could use ## instead of #, that would be nice. I use ## for all other section headings (I think)

I just asked myself: Why do we even have the language headlines (### Java, ### Haskell, ...)? There is always only one programming language visible at a time anyway and we don't add headlines to the smaller code snippets. Honestly, I don't think we need those, but I want to hear what others think.

[Butt4cak3]

Okay. The same question has been answered in another PR. I'd say we finish up this one first (change "Example Code" to ## instead of #) and then remove all the language headlines in another PR.

[leios]

Yeah. Agreed. I want to merge #242 soon, too. I think it will break some PR's, though.

[Butt4cak3]

It shouldn't break too much. Git properly detected all the file moves, so it should be able to handle it.

[leios]

A nice standardization of code titles.

[Wesley-Arrington]

@Butt4cak3 I'll make that PR to remove language headlines :)
