Metacat

1. Modified buildIndex() so that only one connection is used for both indexing nodes and indexing paths.
2. Modified the indexing algo so that indexing of paths is done while nodes are being indexed. Results in a much faster indexing algo
3. Replaced access to NodeRecord.<variable> with NodeRecord.<getVariable>

Change the code level of the MetacatHasDoc harvester operation from "Warning" to "Info". This is to reduce the amount of diagnostic output generated in the email reports to the site contact.

Change the maximum code level reported to the site contact from "info" to "notice". This is to reduce the amount of diagnostic output generated in the email reports to the site contact. Diagnositcs of type "error", "warning", and "notice" will be sent to the site contact, while messages of type "info" and "debug" will not (but they will still be sent to the Harvester Administrator).

Modified the way checkDocumentTable is accessed. Also removed the while loop from the checkDocumentTable. Now if the document is not found, the thread goes to sleep - instead of checking again. (In hope of a more bugfree code)

Replaced access to NodeRecord.<variable> with NodeRecord.<getVariable>

1. Changed teh access modifier from public to private for variables
2. Added a new variable for nodedatanumerical
3. added a new constructor

Moved printMessage statements to inside the if loop so that they are not printed each time getInstance is called

Bug #2207. Metacat Advanced Search interface.
Improvements to Advanced Search form:
(1) Delete keywordSearch() function. Not used in advanced search form.
(2) Re-initialize hidden form values for geographic boundaries.
(3) Change table width to 100% so horizontal rules will span the full width....

Using xml_path_index instead of xml_index to find documents which havnt been indexed.

Replaced hardcoded namespaces with variable defined in metacat.properties
