Right. The from_searchResult() method in SimilarityPair was actually a
humble attempt to integrate the Tools::Blast objects at least a little
bit with the rest of Bioperl (i.e., this method allows you to turn
Blast objects into SeqFeatureI compliant objects). BPlite objects
already inherit from those SeqFeature classes and thereby do not need
such a method. (Obviously, BPlite objects don't implement interfaces
for hits and aligned regions either.)
