Description: Implements functions for working with absorbing Markov
        chains. The implementation is based on the framework described
        in "Toward a unified framework for connectivity that
        disentangles movement and mortality in space and time" by
        Fletcher et al. (2019) <doi:10.1111/ele.13333>, which applies
        them to spatial ecology. This framework incorporates both
        resistance and absorption with spatial absorbing Markov chains
        (SAMC) to provide several short-term and long-term predictions
        for metrics related to connectivity in landscapes. Despite the
        ecological context of the framework, this package can be used
        in any application of absorbing Markov chains.
