Adds display_tables() method to FBS - #246

display_tables:
  <Table 1 title>:
    selection_fields:
      # exactly as used elsewhere
    industry_spec:
      # formatted as elsewhere, but can be used to produce a table that is more aggregated than the underlying FBS
    replace_dict:
      <column>:
        <to_replace>: <new_value>
        <to_replace>: <new_value>
        # etc.
