Additional explanation to the already existing chapters

[TrifanBogdan24]

Here are some changes I made and my approach of Tour of Rust:

• a few words about what is Rust and its unique aspects
• working in terminal with Rust (compiling, running and cargo commands)
• macros
• detailed information about data types and collections
• self and Self in terms of implementing a static / non-static method for a struct
• how to work with cargo

The new explanations are described both in English and Romanian.

[TrifanBogdan24]

Solved issues:

• The explanation of Structures is not clear richardanaya/tour_of_rust#431
• Suggestion for this excellent tutorial richardanaya/tour_of_rust#423
• A bit more about cargo and crates.io richardanaya/tour_of_rust#306
• Explaining macros richardanaya/tour_of_rust#289

Thank you Alexe1289 for the feedback, I hope it is all right now.

Looks good, can you add the changes to the Romanian translation also?

[TrifanBogdan24]

Sure. I will translate as soon as possible the new explanations.

[alexandruradovici]

@TrifanBogdan24 please mark the changes that are fixed as resolved.

[alexandruradovici]

Please format the code in Rust Playground.

The typos, confusing explanations and other similar issues I pointed out a while ago still exist.

[mariapana]

Both the English and the Romanian versions have typos, missing words or situations where the subject of the phrase is in plural form while the verb is in singular form etc. Besides these issues, I also made a few suggestions regarding the clarity of the explanations (which are not mandatory, but could be helpful for inexperienced learners). You can refer to my older comments for concrete examples.

[alexandruradovici]

Please rebase.

[TrifanBogdan24]

@mariapana, I tried correcting the typos.
Do I have your approval before rebasing?

[mariapana]

Looks good!

[TrifanBogdan24]

I hope that my branch, fixing, is rebased.
