When the simulation begins, Acker is wearing _white_ pants, _white_ socks, and a _white_ shirt. The closet shelf, dirty laundry pile, and laundry facilities are all initially empty.  The program starts execution using the special method {{public static void main(String\[\] args)}} in class {{Main}}.  The {{main}} method interface is the only vehicle for executing Java programs directly from the command line. (DrJava has a {{main}} method for this reason.)

Your solution will be graded using the textual interface. GUIs are notoriously difficult to test and all of the GUI code is being provided as support code anyway. Your correctness and testing scores (which each count 25% of your grade) will be based on how well your implementation of each command complies with the given specifications and on how well you demonstrate this compliance with test cases. You can test your DoCommandVisitor using the same approach
given in our TestSample.java class. These tests use the simulate method in Student to drive the execution of
DoCommandVisitor. If you write some utility methods fopr BiLists you should separately test these methods. You are NOT responsible for testing our support code in laundry.zip including the {{BiList} class.

Form of Event Commands

Your program executes a loop that repeatedly reads input from an input "process" that returns Command objects. The input process (provided by our supporting framework) reads a series of event description commands, one to a line, either from the console or from a file. The input process converts a stream of characters to Command objects which are passed to your program.
