Compares self to other using tiptotip distance matrices.
Value returned is dist_f(m1, m2) for the two matrices. Default is to use the Pearson correlation coefficient, with +1 giving a distance of 0 and 1 giving a distance of +1 (the maximum possible value). Depending on the application, you might instead want to use distance_from_r_squared, which counts correlations of both +1 and 1 as identical (0 distance).
Note: automatically strips out the names that don’t match (this is necessary for this method because the distance between nonmatching names and matching names is undefined in the tree where they don’t match, and because we need to reorder the names in the two trees to match up the distance matrices).
Parameters:  other : TreeNode
sample : int or None
dist_f : function
shuffle_f : function


Returns:  float

>>> from skbio.core.tree import TreeNode
>>> # note, only three common taxa between the trees
>>> tree1 = TreeNode.from_newick("((a:1,b:1):2,(c:0.5,X:0.7):3);")
>>> tree2 = TreeNode.from_newick("(((a:1,b:1,Y:1):2,c:3):1,Z:4);")
>>> dist = tree1.compare_tip_distances(tree2)
>>> print "%.9f" % dist
