[Documentation] Specific examples explained on the wiki

[rubyFeedback]

Hey there,

I am modifying existing .cfdg files right now. I noticed that my knowledge
is quite outdated. :-)

We have a wiki here:

https://github.com/MtnViewJohn/context-free/wiki

Would it be possible to also add an "example" subsection near the end,
where simple examples are explained, to genuine newcomers? (This
would include old and forgetful people like me too!)

Does not have to include many examples; perhaps 4-5 examples, and
the explanation does not have to be long. I am currently having a very
hard time understanding other people's cfdg-rules, so my hope is that
this could help us mere mortals to understand what is going on in the
more advanced variants as well, starting from the basic rules. :-)

Thanks!

There are many on the main website and some in the editor! and in the forum
