Giving same cluster id to all records linked from multiple sources #108

[navinrathore]

addUniqueCol() is also referred to TrainingDataFinder.
dropDuplicate() could be expansive, but perhaps necessary. Applied on data from master source only.

Note: addUniqueCol() is also duplicated in FileUtil.java, nowhere used as of now.

Instead of changing trainingdatafinder and addUnqieCol, can we invoke addUniqueCol with id_col and change alignLinked method to make z_cluster same as z_id ?

[navinrathore]

Yes. That's look good. Made the changes.
