Add some flags to rm command

[andywu42]

Objective: Add possible flags to rm so that it can recursively remove directories and files inside of them. Also deletes directories inside of directories. I want to also update rm on its own so that it cannot delete directories.

Ideas:
"-rf" removes all files and directories in a given directory
"-v" verbose flag that displays what is being removed

This is a good idea. I think we might need to add a bit of complexity.

For the -r flag, that should remove all files / dirs. -f would ignore errors / not prompt about it. Which brings me to my next point... you might want to also add an -i option for interactive mode, that prompts Y/N for each file.

It would also be nice to support -d as well, and I think -v is a great idea.
