The code for QueueSearch begins as follows

"public abstract class QueueSearch .... "

The "abstract" keyword implies you cannot instantiate the class. You
need to instantiate one of its concrete subclasses (TreeSearch or
GraphSearch).

The demo and unit test classes have a dozen plus examples of how these
may be instantiated. The readme file explains the two hierarchies of
search and how they relate to each other.

"> I've tried several ways to instantiate it and I keep getting
> complaints from eclipse."

When this happens the next time, do try to understand what the error
message is trying to communicate. An attempt at doing this would have
exposed the "trying to instantiate an abstract class" error.

In other words, eclipse complains for a reason!
