Overview

This class will be helpful in adding support for other OS’s. To add an OS, see how each BaseOs subclass is implemented, implement it, and add it to the list of supported OS’s.

For the purpose of this program, an OS is defined as an approach to getting and setting wifi information. Therefore, although Ubuntu and RedHat are both Linux, they will probably need separate BaseOs subclasses.
