v1.1.0

Added

• Pest movement based on overpopulation (Vaclav Petras)
  • When cell contains too many pests, pests leave and move to a different cell.
• Total hosts added to run_step (Chris Jones)
  • Allows overpopulations to be based on total_hosts rather than total_populations
  • Allows movement to be based on total_hosts rather than total_populations
• Mortality timing is now more flexible (Chris Jones)
  • requires 2 new parameters mortality_frequency and mortality_frequency_n

Changed

• Model class internal attributes and functions are now protected instead of private
  to allow derived classes to access them for greater flexibility (Vaclav Petras).
• Model class kernels are now created and returned by protected functions (Vaclav Petras).
• Config class has now more defaults and subsequent setup now consistently fails when
  required values were not set (Vaclav Petras).
• Movement module has added parameters (mortality_tracker_vector, exposed, resistant,
  total_exposed, and suitable_cells) (Chris Jones).
  • Now moves exposed and resistant populations
  • Now moves total_hosts
  • Now moves moratility tracked hosts
  • Adds a new suitable_cell if a movement creates a new location with hosts.
• Treatments now modify total hosts (Chris Jones)
• Citation updated to PoPS Frontiers paper (Chris Jones)
  • Jones, C., Jones, S., Petrasova, A., Petras, V., Gaydos, D.,
    Skrip, M., Takeuchi, Y., Bigsby, K., and Meentemeyer, R., 2021.
