[Biojava-l] Recursion of FeatureFilters

[Matthew Pocock]

Hi Mark.

Good questions. The feature filters will not alter the feature objects, 
so if you use a filter to get a gene feature, it will still have all of 
its children attached as well as its parents. If you filter with the 
recurse parameter as false, it will only scan the emediate children. If 
it is true, it will scan all descendants.

For example, filtering with accept all will return you a feature holder 
containing all decendants of that feature, and you can still go to each 
of these and get at the children they had as per normal.

There are now a couple of filters that pull features out based upon 
properties of other features with defined relationship (e.g. fetch me 
all features with assembly parents).
