Explanations & Wikipedia URL as comments at top of .rs code

[wilsonmar]

Even though algorithms are among the most complex coding,
Algorithm .rs files current have no comments explaining what it's about.

There was a https://github.com/TheAlgorithms/Algorithms-Explanation
But the last entry was October 2025 when entries cover only a few of the 393 .rs files within Rust's Algorithms collection.

So how about we move what's already in the Algorithms-Explanation into individual .rs files,
such as this example:

// [Aho-Corasick Algorithm](./aho_corasick.rs)
// at https://github.com/TheAlgorithms/Rust/blob/master/src/string/aho_corasick.rs
// https://en.wikipedia.org/wiki/Aho%E2%80%93Corasick_algorithm
// A string-searching algorithm invented by Alfred V. Aho and Margaret J. Corasick in 1975.[1] 
// A kind of dictionary-matching algorithm that locates elements of a finite set of strings 
// (the "dictionary") within an input text. It matches all strings simultaneously.

Authors of each algorithm can then add to their own .rs file.
