public class DrillDownPathBean
extends Object
This class represents a facet object bean. facet object defines the hierarchical fieldName,
which can be drilled down. This can be used as a value in a record.
Example :

Then the record field : value pairs will be, e.g.
Price : $50.00
Author : firstName LastName
ISBN : 234325435445435436
Published Date : "1987" , "March", "21"
Here Publish Date will be a facet/categoryPath, since it can be drilled down to Year, then month and date
and categorizes by each level.
