Neither a bug, nor a feature request, more an improvement. I will maybe do a PR myself, but gotta get than assignment done first...

Expected Behavior

all *DegreeRangeBuilders should return corresponding types, when getFilter() is called.

Current Behavior

The OutDegreeRangeBuilder returns a generic Object of interface type Filter, InDegreeRangeBuilder and DegreeRangeBuilder return the specialized internal object InDegreeRangeFilter and DegreeRangeFilter respectively.

Possible Solution

all three should probably return a RangeFilter and the setRange() method should be declared in that interface and overwritten in DegreeRangeFilter, InDegreeRangeFilter and OutDegreeRangeFilter

Steps to Reproduce

var f1 = new OutDegreeRangeBuilder.getFilter() // returns a Filter
var f2 = new InDegreeRangeBuilder.getFilter() // returns a InDegreeRangeFilter
var f3 = new DegreeRangeBuilder.getFilter() // returns a DegreeRangeFilter

Context

when using the gephi-toolkit with there filters, one has to cast the result of OutDegreeRangeFilter.getFilter() to set the range.
