 * @brief A main driver that provides some rudimentary tests for row.cpp
 * Tests involving memory leaks were tested using valgrind via the command:
 * `valgrind ./lab2` Test output was left in submission to signify modules
 * that have successfully passed and provide further clarity of testing
 * methods.
