Metacat

Adding a new method to MetaCatServlet for getting the value of paths to be indexed from metacat.properties file and indexing those paths in xml_path_index

Changed the name of the function

Added a new function which can used to control the carriage return at the end of the debug message and 'Metacat' in front of the message...

Fixed a bug in printSQL function. The bug came into the picture for queries which involve multiple query groups and one of the query groups does a % search.

Added code to delete all entries in xml_queryresult table when buildIndex for a docid is called.

Adding the call to normalize function for now -- too many calls to normalize function are made and this needs to be looked into. Removing call to normalize function caused trouble in text like this "A&B"

Fixed a bug in last commit. Doing a search like
pathquery version="1.2">
<returndoctype>eml://ecoinformatics.org/eml-2.0.0</returndoctype><returnfield>originator/individualName/surName</returnfield><querygroup operator="INTERSECT"><queryterm casesensitive="false" searchmode="contains"><value>%</value></queryterm><queryterm casesensitive="false" searchmode="contains"><value>National Center for Ecological Analysis and Synthesis</value><pathexpr>organizationName</pathexpr></queryterm></querygroup></pathquery>...

Fixed a bug - when returnfield_id is not found in xml_returnfield, records are not added to xml_queryresults

1. removed the call to QuerySpecification.printAttributeSQL() from QuerySpecification.printExtendedSQL()
2. in QuerySpecification.printExtendedSQL() if ( returnFieldList.size() == 0 ) then it returns null
3. DBQuery.addReturnfield() doesnt execute the element query if printExtendedSQL returns null

A minor change from containAtrributeReturnField to
containsAttributeReturnField
