Changes in version 1.1.1                        

Major changes

  - Added mutualism boolean for simulation
  - Switch hs_mode from a boolean to a string. Can now use switch,
    spread, or both.

Bug fixes

  - Fixed a bug where instead of skipping a replicate when using
    summarize_cophy the function would stop when encountering a dataset
    where the Parafit couldn't be calculated.
  - Fixed a bug where summarize_1cophy would have NA as the column name
    if the column value had NA

                 Changes in version 1.1.0 (2021-03-02)                  

Major changes

  - Function names shortened to be more user friendly
  - Added functionality for plotting events on cophylogeny from
    event_history data frame
  - sim_cophyloBD (formerly sim_cophylo_bdp) now has two arguments:
      - host_limit controlling the number of hosts a symbiont is allowed
        to have at one time
      - hs_mode which changes host expansion events to host switch
        events (h_exp_r is still used to change the rate)
  - Added new simulation mode sim_cophyloBD_ana which adds anagenetic
    events (i.e., happening between speciation nodes) to the
    functionality of sim_cophyloBD
  - Changed event history to output only major events (description of
    abbreviations added to documentation)
  - show_div_bar option added to plot. This outputs a bar showing the
    different events as tick marks.
  - swapped output of association_mat from hosts in columns and
    symbionts in rows to hosts in rows and symbionts in columns.

                 Changes in version 1.0.0 (2020-10-06)                  

Major changes

  - First release of software can currently simulate:
    
      - species trees
      - host-symbiont paired trees
      - locus trees within host, symbiont, or species trees
      - gene trees within locus trees using the multilocus coalescent
      - gene trees within species trees using the multispecies
        coalescent

  - Other features:
    
      - plotting of host-symbiont paired trees that include extinct tips
      - limited functions for using the simulated trees
