Scons compilation examples

[Amaras]

This PR aims to provide examples on how to create compilation (and run) instructions with SCons, as per #691.
As this is currently the only effort to provide concrete examples of compilation instructions, I highly encourage others to open their own draft PRs with their own compilation instructions, until we decide what system to use.
I'd like to give the systems a fair comparison, so try to provide them for the same chapter(s) as I did (in other words, please don't get too ahead of me.)

Below is a basic instruction manual for the Barnsley Fern chapter

How to use (e.g. create the out.dat or barnsley.dat file)

1. go to the directory you want to compile code for;
2. run scons out.dat or scons barnsley.dat (depending on the implementation)
3. (optional) clean the directory with scons -c . to remove all the intermediate and final files.

Note: if you want to only clean the out.dat file and keep the executables/classes (and so on) files, you can run scons -c out.dat

Hum... I think I branched off a PR branch... I'll try to get it correct later or reopen the PR branching off master.

The point still stands, as there should not be a problem with that (especially since the SCons PR should be merged after the C++ flood fill one)

Are we doing it this way as opposed to @stormofice 's implementation

This is one way to do it. I'm not sure if it's the best way.

Does SCons work with every language?

Regardless of that, I don't see why this would interfere with the verifier, as better compilation/running instructions would just simplify the language configuration files.

Does SCons work with every language?

Out of the box, SCons works with C/C++, Fortran, D, TeX/LaTeX, Java, some Assembler languages, and some other languages. We'd probably need to provide Builders to ensure consistent compilation for Rust, Scala, etc.
You can see #691 for more detail about my questioning

I think this is fine and if it makes things easier for @stormofice, then let's do it!

I will say that we probably don't need the flood fill example in this PR, though

Yeah, I'm not exactly sure how to remove the flood fill thingy, properly :/

[Amaras]

I'm not sure if I removed the previous branch commits properly, but it should be okay.

Because we chose to go with the single SConstruct approach, I will close this PR, because it's not relevant.
