%description
Enables quick calibration of radiocarbon dates under various calibration
curves (including user generated ones); age-depth modelling as per the
algorithm of Haslett and Parnell (2008)
<DOI:10.1111/j.1467-9876.2008.00623.x>; Relative sea level rate estimation
incorporating time uncertainty in polynomial regression models (Parnell
and Gehrels 2015) <DOI:10.1002/9781118452547.ch32>; non-parametric phase
modelling via Gaussian mixtures as a means to determine the activity of a
site (and as an alternative to the Oxcal function SUM; currently
unpublished), and reverse calibration of dates from calibrated into
un-calibrated years (also unpublished).
