Library enhancement proposal for copying data from/to Reader/Writer InputStream/OutputStream

Well I will then suggest using IOUtils with two simple methods:

public static long copy(InputStream source, OutputStream target)

public static long copy(Readable source, Appendable target)

>>> To speed things along for now i recommend creating a new class say IOUtils or preferably ByteStreams. 
>> Hmm, in the case of Reader/Writer ByteStreams seams to be a bit confusing for me, should then the reader copy stuff go to also a separate class like „CharStreams“. Locally I created an implementation named „IOUtils“ containing a copy method for InputStream to OutputStream.
