--[[ Configuration table
Whenever asked for a "config", the following table structure is expected:
config = {
skip_empty_tables = false -- if true, does not store empty tables
-- On next read, keys that mapped to empty tables resolve to nil
-- Used by: write_table_to_file
}
Not all functions use all of the parameters, so you can simplify your config sometimes
