 -- TODO:
--- - Redefine mediant-search functions to return the deepest depth. Meant for
---   use with making tables. (Instead of ratios and depths, it's ratios, depths,
---   and deepest_depth.) Existing function calls will work the same as before,
---   and modules making a table can use this accordingly. ALT IMPLEMENTATION:
---   a helper function that returns the deepest depth, when a table of depths is
---   passed in.
 -- - Add a convert-to-rational function.
