//Bitset using classes may well go away as will other classes that
//provide support for Single Index/Boundary docs implementations

//Appears to load xml based metadata -- move to lgConverter or lexevs-dao

//Supporting classes for the metadata.xml file and a variety of other things that can mostly go away

//Supporting code for the older version of the multi-index search. 
//Will review but largely re-implement in lexevs-dao
//These classes are called by the classes in the dao project, but many method calls may not be called
//or otherwise affect API level calls.

//This package looks to have been replaced to some extent by LuceneLoaderCodeIndexer in the lexevs-dao project
//where it builds documents from entities.
//but it has quite a lot of calling code so we'll have to make sure all the paths are dead ends before eliminating it.
edu.mayo.informatics.indexer.api.generators

//Quite a bit of the methods and classes have a presence in lexevs-dao
//Many seem not be be called by upper level API classes and appear to be dead execution paths 
//These will take some time to evaluate, refactor and test.

//Used by the WhiteSpace analyzer.  We will move this into the lexevs-dao

//This appears to be a regex query wrapper.  We'll want to move it to lexevs-dao

//Exceptions package.  We'll consider simplifying or removing it in favor of rethrowing runtime exceptions.
