Revert "test to send to Jonatans branch"

This reverts commit c67639496838a79ddf5b2269e35ed3d89ea68291.
added Elcin's AddList method and UnitTest3

Added the code that Elcin wrote to github. Also created a UnitTest3()
method. I would add some defence. For example, check to see if the list
name that is being created already exists and send warnign message.
Also, add columns to new list.
