* This file is the main driver for Lab 12, which will  *
* demonstrate opening files and validating command line*
* arguments in addition the following linked list ops: *
*   - creating a linked list with a separate head node *
*   - deleting a specific node from the linked list    *
*   - printing the linked list                         *
*   - calling a function that deletes the linked list  *
