Writes data to a <code>DataOutputStream</code>. This method is used
primarily by GUI clients which need to download OPeNDAP data, manipulate
it, and then re-save it as a binary file.

@param sink a <code>DataOutputStream</code> to write to.
@throws IOException thrown on any <code>OutputStream</code>
exception.
