      public class PdeEmitter
      extends Object
      implements PdeTokenTypes

  PDEEmitter: A class that can take an ANTLR Java AST and produce reasonably formatted Java code from it. To use it, create a PDEEmitter object, call setOut() if you want to print to something other than System.out, and then call print(), passing the AST. Typically, the AST node that you pass would be the root of a tree - the ROOT_ID node that represents a Java file. Modified March 2010 to support Java 5 type arguments and for loops by

          public PdeEmitter(PdePreprocessor pdePreprocessor,
                    PrintWriter out)

    - #### print

          public void print(AST ast)
                     throws SketchException

      Print the given AST. Call this function to print your PDE code. It works by making recursive calls to print children. So the code below is one big "switch" statement on the passed AST type.
      Throws:
        `SketchException`
