Helper ideas

[llamicron]

Here's a list of ideas for helper functions/modules. These are designed to help people write criteria, especially people who aren't very familiar with rust. Even if it just saves a few lines of code, it might be worth it. For example, there's a file_exists helper, even though you can check that in a couple of lines with a PathBuf. I'm expecting people who just got introduced to rust to use it (if anyone uses it lmao)

CLI

• CLI Command runner - run a command and handle the platform specifics, return stdout and stderr and all that fancy stuff. Basically just do Command::new() and handle the platform differences
• Confirmation - pause the thread and ask for confirmation before continuing. Also add y/n confirmation.

System

• Program installed - add a check to see if a program is installed
• Get program version - This is now the Program enum and Version struct under the system helpers module

Web

• Post arbitrary data - currently the only post helper can only send something that can be deserialized into json. Maybe add a separate method where you can post any string data
• Get IP - Get the public IP of the system, if there is one.

#1fcaa69 add's a Version struct

Program shouldn't be under cli, there should be a system module. This stuck out to me when rereading the example grader
