`data`	[`list()`] [`data.table()`] for each type of data input for the model (currently only 'population'). See Section: Data for more information.
`settings`	[`list()`] Named list of settings for running the popReconstruct model with. The required settings are the same as those required for `demCore::ccmpp()`, see Section: Settings for these. The optional settings specific to popReconstruct are described in Section: Optional popReconstruct Settings
`detailed_settings`	[`list()`] Detailed settings for each ccmpp input and 'population'.
`value_col`	[`character(1)`] Name of the column containing the value of interest in each of the `inputs`. Default is 'value'.
