Simulates demic diffusion building on models previously developed
for the expansion of Neolithic and other food-producing economies during
the Holocene (Fort et al. (2012) <doi:10.7183/0002-7316.77.2.203>, Souza et al.
(2021) <doi:10.1098/rsif.2021.0499>). Growth and emigration are modelled as
density-dependent processes using logistic growth and an asymptotic threshold
model. Environmental and terrain layers, which can change over time, affect
carrying capacity, growth and mobility. Multiple centres of origin with
their respective starting times can be specified.
