Selects a random code file to read

Helper to randomly pick some code to read

Inspired by Adam Wołk's blogpost about reading BSD code daily.

The idea is to pick a project (or a few) and read at least one source code file a day for educational purposes. He chose BSD's base system and userland, I have chosen the Linux kernel and some GNU system utilities.

Which projects will you chose?

Add an argument to ignore entries

Add an argument, "-i" / "--ignore" sounds good, to ignore entries. So for example you could ignore the drivers folder in the kernel tree, by doing "-i drivers".

Add an argument to select file extension to look for

C files are the default but there could be an argument (-e or similar) to change this to ".py", ".rs", ".js", etc

Select number of random files to print out

Maybe the user wants to see 5 random files to then chose the one that looks the most interesting. Add an argument to select how many files are printed out, having 1 as the default.

Handle case of no files found

When there isn't a single file found rng.gen_range(0, files.len()) will explode.

Handle this by printing out there are no files found and exiting.

Change unwrap() to a match

let file_path = entry.path().to_str().unwrap();

should do a match and ignore the file if the path isn't valid.
