valid_file: a Boolean indicating whether or not the control file path is valid
keywords: a hardcoded list of the keywords that should be present in the control file
blanks_okay: a hardcoded list of whether each keyword can be blank (based on order of keywords)
valid_structure, no_incorrect_blanks: Boolean keywords based on internal checks of the control file format

population_path: a string representing the path to the population data file
verbose: a Boolean indicating whether the user wants to run in verbose mode
output_exposure: a Boolean indicating whether exposure should be output
detailed_conc: a Boolean indicating whether concentrations should should be output as totals or by pollutant

check_path: checks if a file exists at the given control file path
get_input_value: gets the input for a given keyword
check_control_file: runs all of the internal checks to confirm the control file is valid
get_all_inputs: imports all values from the control file
get_region_dict: loads all of the acceptable values for the various regions
region_check_helper: a helper function for checking the region of interest and region category inputs
out_res_check_helper: a helper function for checking the output resolution input
check_inputs: checks that all inputs are valid once imported
