checking in timing print statments

Add a new method to print out more effecient query.

Add new data structure and method to handle query terms which have same search value.

Add a new method to compare the query terms to see if they have same search value.

Get rid of user_owner=public part in access query.

reformatted a bit and removed unneeded code

paging now works well. sped up the caching by using SAX instead of DOM parsing. it seems fast. need some other people to test for me though. the two params needed are 'pagesize' and 'pagestart'. I haven't updated any of the web interfaces to use this, so if you want to try it, you'll have to type in the url the old fashioned way

Add a new overload method - createResultDocument and add a new check for null.

got paging working. metacat also now caches resultsets for users' sessions. the paging is a bit slow, due to some xpath statements. i need to get this optimized now.
