+Description
+STELAR is a method (written in Java) for estimating species trees given a set of rooted gene trees, such that triplet consistency (between a species tree and the gene trees) is maximized within a constrained search space. 
+The algorithm used is described in our paper STELAR: A statistically consistent coalescent-based species trees estimation method by maximizing triplet consistency".

+STELAR code uses code from the PhyloNet package by Luay Nakhleh (bioinfo.cs.rice.edu/phylonet). 
+The Phylonet code base was subsequently used by DynaDup and ASTRAL (with permission from Authors), and STELAR is mostly based on DynaDup code base.
