* Initialize the stream copier.
* If neither the source nor the sink are buffered, buffering will
* be automatically added to the sink.
* @param aSource
* contains the data to be copied.
* @param aSink
* specifies the destination for the data.
* @param aTarget
* specifies the thread on which the copy will occur. a null value
* is permitted and will cause the copy to occur on an unspecified
* background thread.
* @param aChunkSize
* specifies how many bytes to read/write at a time. this controls
* the granularity of the copying. it should match the segment size
* of the "buffered" streams involved.
* @param aCloseSource
* true if aSource should be closed after copying (this is generally
* the desired behavior).
* @param aCloseSink
* true if aSink should be closed after copying (this is generally
* the desired behavior).
