These files are used to create a new function called indexfromcollection which can create a lucene index from a collection folder. "builtin-functions.xml" and "pom.xml" have been modified to depend on lucene and create the new function. "IndexConstructorScalarEvaluatorFactory" should be placed in the runtime.functions.node package. The last two files, "IndexBuilderElementPath" and "IndexElement" are classes that should be added to a new package called "org.apache.vxquery.index"
