I have heard about your library from a friend and badly i haven't found some kind of template binary tree implementation... What i'm working on is a multi dimensional binary tree to make Quadtrees Octrees or more.... And I want to make genericity to put several types of object in the same Leaf of my tree... I think this idea sounds like a cool stuff ...Is there laready any structure in Boost that can be use like it ? Or What do you think of this feature? ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************
