taxodist: Taxonomic Distance and Phylogenetic Lineage Computation

Computes phylogenetic distances between any two taxa using hierarchical lineage data retrieved from The Taxonomicon <http://taxonomicon.taxonomy.nl>, a comprehensive curated classification of all life based on Systema Naturae 2000 (Brands, 1989 <http://taxonomicon.taxonomy.nl>). Given any two taxon names, retrieves their full lineages, identifies the most recent common ancestor (MRCA), and computes a dissimilarity index based on the depth of the most recent common ancestor. Supports individual distance queries, pairwise distance matrices, clade filtering, and lineage utilities.
