[MarkLogic Dev General] Java XCC save query result to file

   Simple.  Call asString() on the ResultSequence object
and write the String to a file.  Or asStrings() if you
want a separate String for each item in the sequence to
send to different files.

   Or, if the result is truly streaming (see the setCacheResult())
method of the RequestOptions class, streaming is not the default),
you can use the writeTo() methods on the ResultItem(s) in the
ResultSequence.  These take an open Writer or OutputStream and
copy the data across.  They work if you're not streaming, as well.

   There is an example in the XCC JavaDocs that might be helpful.
Go to http://community.marklogic.com/pubs/5.0/javadoc/index.html,
click the com.marklogic.xcc.examples package and then ContentFetcher
class (top one).  Look for the "Click here for the source code for
this class" link just above the Constructor Summary heading.
