Calculates the number of four-taxon subtrees consistent with a pair
of cladograms, calculating the symmetric quartet distance of Bandelt & Dress
(1986), Reconstructing the shape of a tree from observed dissimilarity data,
Advances in Applied Mathematics, 7, 309-343 <doi:10.1016/0196-8858(86)90038-2>,
and using the tqDist algorithm of Sand et al. (2014), tqDist: a library for
computing the quartet and triplet distances between binary or general trees,
Bioinformatics, 30, 2079–2080 <doi:10.1093/bioinformatics/btu157>
for pairs of binary trees.
