      public class DelegatingPreparedStatement
      extends DelegatingStatement
      implements PreparedStatement

  A base delegating implementation of `PreparedStatement`.

  All of the methods from the `PreparedStatement` interface simply check to see that the `PreparedStatement` is active, and call the corresponding method on the "delegate" provided in my constructor.

  Extends AbandonedTrace to implement Statement tracking and logging of code which created the Statement. Tracking the Statement ensures that the Connection which created it can close any open Statement's on Connection close.
