extract_calibrations_phylo

This function extracts node ages for each taxon
pair given in <code>input$tip.labels</code>. It applies the congruification method
described in Eastman et al. (2013) tools:::Rd_expr_doi("10.1111/2041-210X.12051"),
implemented with the function <code>geiger::congruify.phylo()</code>, to create a
<code>data.frame</code> of taxon pair node ages that can be used as secondary calibrations.

Methods and workflows to get chronograms (i.e., phylogenetic trees with branch lengths
proportional to time), using open, peer-reviewed, state-of-the-art scientific data on time of lineage divergence.
This package constitutes the main underlying code of the DateLife web service
at <https://www.datelife.org>. To obtain a single summary chronogram from a group of
relevant chronograms, we implement the Super Distance Matrix (SDM) method
described in Criscuolo et al. (2006) <doi:10.1080/10635150600969872>.
To find the grove of chronograms with a sufficiently overlapping set of taxa
for summarizing, we implement theorem 1.1. from Ané et al. (2009)
<doi:10.1007/s00026-009-0017-x>.
A given phylogenetic tree can be dated using time of lineage divergence data
as secondary calibrations (with caution, see Schenk (2016) <doi:10.1371/journal.pone.0148228>).
To obtain and apply secondary calibrations, the package implements the congruification method described
in Eastman et al. (2013) <doi:10.1111/2041-210X.12051>. Tree dating can be performed with different methods
including BLADJ (Webb et al. (2008) <doi:10.1093/bioinformatics/btn358>), PATHd8
(Britton et al. (2007) <doi:10.1080/10635150701613783>), mrBayes (Huelsenbeck
and Ronquist (2001) <doi:10.1093/bioinformatics/17.8.754>), and treePL (Smith
and O'Meara (2012) <doi:10.1093/bioinformatics/bts492>).
