simplexPrepare

Outline the 2-d probability simplex, and draw the T1 or T3 model points for quartet frequencies.
The models "T1" and "T3" are described more fully by MAR19;textualMSCquartets.

Methods for analyzing and using quartets displayed on a collection
of gene trees, primarily to make inferences about the species tree or network
under the multi-species coalescent model. These include quartet hypothesis tests
for the model, as developed by Mitchell et al. (2019) <doi:10.1214/19-EJS1576>,
simplex plots of quartet concordance factors as presented by Allman et al. (2020)
<doi:10.1101/2020.02.13.948083>, species tree inference methods based on quartet
distances of Rhodes (2019) <doi:10.1109/TCBB.2019.2917204> and Yourdkhani and
Rhodes (2019) <doi:10.1007/s11538-020-00773-4>, the NANUQ algorithm for inference
of level-1 species networks of Allman et al. (2019) <doi:10.1186/s13015-019-0159-2>,
the TINNIK algorithm for inference of the tree of blobs of an arbitrary
network of Allman et al.(2022) <doi:10.1007/s00285-022-01838-9>, and
NANUQ+ routines for resolving multifurcations in the tree of blobs to cycles as in
Allman et al.(2024) (forthcoming).
