 /**
  * A processor that verifies the explicit and implicit constraints in
  * the Filer contract are maintained:
  *
  * <blockquote>
  *
  *  During each run of an annotation processing tool, a file with a
  *  given pathname may be created only once. If that file already
  *  exists before the first attempt to create it, the old contents
  *  will be deleted. Any subsequent attempt to create the same file
  *  during a run will throw a FilerException, as will attempting to
  *  open both a class file and source file for the same type name.
  *
  * </blockquote>
  *
  * Specific checks will include:
  *
  * <ul>
  *
  * <li> Source and class files can be written to from either a Writer or an OutputStream.
  *
  * <li> Calling close multiple times does not re-register the file for
  * processing.
