New function: fishtree_complete_phylogeny, gets complete phylogenies where unsampled taxa were placed using stochastic polytomy resolution.
Use package memoise instead of rolling our own caching functionality.
New global option fishtree.quiet: when set to FALSE, be more verbose during downloads (can help with debugging issues).
Some internal reorganization
New function: fishtree_rogues, identifies rogue/intruder taxa that break the monophyly of a selected group.
fishtree_phylogeny now permits downloads of MRCA trees for paraphyletic groups. Suggested by an anonymous reviewer.
fishtree_taxonomy revamped. It now takes a single argument ranks = ... where you can retrieve taxonomic information for any valid taxonomic rank in our taxonomy. Calling it without arguments returns a data frame of all valid taxa names. Suggested by an anonymous reviewer.
Initial release.
