-     public class DirectReader
      extends Object

  Retrieves an instance previously written by `DirectWriter`

  Example usage:

         int bitsPerValue = 100;
         IndexInput in = dir.openInput("packed", IOContext.DEFAULT);
         LongValues values = DirectReader.getInstance(in.randomAccessSlice(start, end), bitsPerValue);
         for (int i = 0; i < numValues; i++) {
           long value = values.get(i);
         }
