`n_sim`	numeric, number of simulations
`cores`	numeric, number of cores to run in parallel
`get_detection_time`	logical
`travel_dispersion`	numeric
`allow_travel_variance`	logical
`print_progress`	logical
`param_list`	list, with the following elements `incub_mean_log` numeric, the mean_log parameter for the lnorm distribution for the incubation period `incub_sd_log` numeric, the sd_log parameter for the lnorm distribution for the incubation period `inf_period_nohosp_mean` numeric, the mean parameter of a truncated normal distribution for the infectious period for non-hospitalized infections `inf_period_nohosp_sd` numeric, the sd parameter of a truncated normal distribution for the infectious period for non-hospitalized infections `inf_period_hosp_mean_log` numeric, the log-mean parameter of a log-normal distribution for the infectious period for time to hospitalization `inf_period_hosp_sd_log` numeric, the log-sd parameter of a log-normal distribution for the infectious period for time to hospitalization `p_report_source` numeric vector of length 2, currently the probability of reporting by source with the first indicating Hubei reporting and second indicating everywhere else (UPDATE WITH THESE https://cmmid.github.io/topics/covid19/severity/global_cfr_estimates.html) `shift_incid_days` lag from infection to report `delta` days per time period
`drop_zeros`	Whether to drop zeros from results to speed up and reduce file sizes
`file_nums`	File numbers to input if the simualation got interrupted
`dest`	character string, name of destination to simulate importations for
`dest_type`	character string, options: "airport", "city", "state", "country"
`dest_0`	optional character string, specify a higher level destination (i.e. dest_0="USA"), default NULL
`dest_0_type`	optional character string, must specify if specifying a 'dest_0' option; default=NULL
`dest_aggr_level`	character string, level to which travel will be aggregated for destination. Includes "airport", "city", "state", "country", "metro" (only available for CA currently)
`project_name`	character string
`version`	character string
`batch`	character string
`end_date`	Date, last import date
`n_top_dests`	Number of destinations to include, ranked by volume; default (Inf) is all.
