* Note - the calling class should call the {@link #available()} method to detect end-of-buffer
* and move to the next data block when the current is exhausted.
* For optimisation reasons, no error handling is performed in this class. Thus, mistakes in
* calling code ran may raise ugly exceptions here, like {@link ArrayIndexOutOfBoundsException},
* etc .<p/>
*
* The multi-byte primitive input methods ({@link #readUShortLE()}, {@link #readIntLE()} and
* {@link #readLongLE()}) have corresponding 'spanning read' methods which (when required) perform
* a read across the block boundary. These spanning read methods take the previous
* {@link DataInputBlock} as a parameter.
* Reads of larger amounts of data (into <tt>byte</tt> array buffers) must be managed by the caller
