Render an internal type

kiara has a sort of loose framework that helps when there is a requirement to render an internal kiara model instance into some external format. This has developed in a sort of ad-hoc manner, because requirements where this is the solution to where not very clearly (or at all) defined initially, the continued to surface until at some stage I got tired of implementing the same thing over and over again. At the same token, none of this seemed to ever be exposed to higher levels, which is why I never bothered to fix its API etc.

cli usage

To see what sort of functionality is possible with this, explore the kiara render command. Which, up to a point should be self-exploratory.
