:: This code pretty-prints a variety of things using the `xray` and
:: `plum` libraries:
::
:: - `render-vase`: Renders the data in a vase.=$-(vase wain)
:: - `render-hoon`: Pretty-prints a `hoon` AST as hoon code.
:: - `render-type`: Pretty-prints a type as a hoon expression.
:: - `render-type-simple`: Debug-print for the `type` structure.
:: - `render-vase-with-type`: Pretty print a vase: both value and type.
::
:: There's a lot of logic here, but most of it is fairly
:: straight-forward.
::
:: XX Output for cords is ugly. Why ~~a instead of 'a'?
