/**
* These are the branches in our tree, each branch forms a complete query that
* could be sent to the main bugset to return all the bugs it contains For
* example, a single bugAspects could be <priority,high> or it could be
* <priority,high>, <designation,must fix>,<class,fishpond>,<package,default>
*
* In this implementation, <priority,high>,<designation,unclassified> is
* different from <designation,unclassified>,<priority,high>. (I'm not talking
* about the fact we use the .equals from ArrayList, I'm talking about what a
* query would return, though both are true) For a speed boost, this class could
* be rewritten to make these equal, BugSet could be rewritten to cache full
* queries off the main BugSet, (instead of caching each part of the query
* separately in the BugSets created) and resetData could be rewritten to work
* more like Swing's validate, only clearing data if the data is wrong. This
* would save time after changing certain aspects of the tree. Just an idea, I
* wouldn't suggest it unless its absolutely necessary. -Dan
