Examples cleanup

[zrzka]

• Removed logging example from the README.md
  • There's no such example
• Fixed some typos
• Moved examples/program_examples/command_bar.rs to examples/command_bar.rs
  • Otherwise you can't run it with cargo run --example command_bar
• Excluded examples/program_examples from the workspace
  • Otherwise you can't run snake & first_depth_search, see below

$ cd examples/program_examples/snake
$ cargo run
cargo run
error: current package believes it's in a workspace when it's not:
current:   /Users/robertvojta/Projects/personal/crossterm/examples/program_examples/snake/Cargo.toml
workspace: /Users/robertvojta/Projects/personal/crossterm/Cargo.toml

this may be fixable by adding `examples/program_examples/snake` to the `workspace.members` array of the manifest located at: /Users/robertvojta/Projects/personal/crossterm/Cargo.toml
Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude` array, or add an empty `[workspace]` table to the package's manifest.

Thanks for the contributions!

Nice, altough is that a requirement, because I believe it is excluded by default right?

[zrzka]

It's excluded in a way you can't do stuff like cargo run --example snake. But w/o this section, you can't run snake via cargo run even if you're in the snake folder.

right, I didn't know of that option, I was looking for that behavior, previously I would just put it in the 'member' tags, run it, and remove it, but that feels hacky and it is. Thanks for pointing out the alternative.
