add numTrees():int property to RevTree

Similar to RevTree.size(), RevTree.numTrees() allows to quickly inspect whether a given RevTree has

features recursively in the tree, numTrees() returns only the number of tree entries that are direct
children of the tree
improved DepthTreeIterator to quickly handle the RECURSIVE_TREES_ONLY strategy
