Metacat

Add code to initialize Options and some code clean up

Add code to initialize Options. Otherwise will get null exception.

Test file to see how long it will take to build records in xml_queryresult table.

Add a new test to test new query method with qformat.

Add more test (update) on upload

Delete a test for printAttributeQuery which was delete from java file.

Test file for query group.

A query client to test metacat performance

Added a new class called Sitemap that is used to generate a series of XML documents representing the URLs of metacat documents following the sitemap protocol. The Sitemap class extends TimerTask so that it can be scheduled to run once a day or so. New configuration options were added to metacat.properties to control where the sitemaps are written and hw often they are updated. By default we do it once a day, as more often is overkill for search engines....

Currently every MetacatClientTest will generate new doicd and the the docid will be reused. So it will generate problem. I add new method to persistent the doicd in a file and this problem was fixed.
