Class ByteBufferIndexInput

Base IndexInput implementation that uses an array of J2N.IO.ByteBuffers to represent a file.

Because Java's J2N.IO.ByteBuffer uses an System.Int32 to address the values, it's necessary to access a file greater System.Int32.MaxValue in size using multiple byte buffers.

For efficiency, this class requires that the buffers are a power-of-two (chunkSizePower).
