public ByteArrayOutputStream decompress( InputStream compressedIn, int expectedDecompressedLength ) throws IOException {
		return decompress( compressedIn, expectedDecompressedLength, false );
	}
Creates a new decompressor. 
If the parameter 'nowrap' is true then the ZLIB header and checksum fields will not be used. 
This provides compatibility with the compression format used by both GZIP and PKZIP.
Note: When using the 'nowrap' option it is also necessary to provide an extra "dummy" byte as input. 
This is required by the ZLIB native library in order to support certain optimizations.
@param compressedIn an input stream containing the compressed data
@param expectedDecompressedLength the expected length of the decompressed data
@return an output stream containing the decompressed data
@throws IOException
