Title: Optimal Project Prioritization
Description: A decision support tool for prioritizing conservation projects.
    Prioritizations can be developed by maximizing expected feature richness,
    expected phylogenetic diversity, the number of features that meet
    persistence targets, or identifying a set of projects that meet persistence
    targets for minimal cost. Constraints (e.g. lock in specific actions) and
    feature weights can also be specified to further customize prioritizations.
    After defining a project prioritization problem, solutions can be obtained
    using exact algorithms, heuristic algorithms, or random processes. In
    particular, it is recommended to install the 'Gurobi' optimizer (available
    from <https://www.gurobi.com>) because it can identify optimal solutions
    very quickly. The 'rcbc' R package (available at
    <https://github.com/dirkschumacher/rcbc>) can also be used to generate
    solutions using the CBC optimization software
    (<https://github.com/coin-or/Cbc>). Finally, methods are provided for
    comparing different prioritizations and evaluating their benefits.
