Example on making TabAutoComplete commands!

So I looked on line for awhile on spigot and I could not find an example on how to make TabAutoComplete commands. So I decided to start experimenting and find out how to do TabAutoComplete in commands. once I found out how to do this I made an example plugin.

Down below is the source code to my basic example plugin with TabAutoComplete commands. Feel free to use this in your plugin because I feel like this is very useful for plugins that have a lot of arguments in there commands.
