Program synopsis:
java gshute.trees.SearchTreeTester nodeClass [ file ]

If this program is executed with no file name argument then it executes commands entered from the terminal. If it is executed with a single file name argument then the program attempts to open the named file and execute the commands in it. If the open fails, or if there is more than one file name argument, then the program terminates with an error message.

The nodeClass argument must be the name of a subclass of the TreeNode class. The subclass should have a constructor with a single Object parameter. This constructor is used to build trees for this program. The constructor should call the superclass constructor to ensure that the parameter is installed as the data for the node that is created by the constructor.
