Plan: Fix errors and clean up this project

[Dane Finlay]

I wrote this library many years ago now. There are a number of problems with it. It's a bit of a mess, really. It needs to be redesigned.

My plan is to clean up it for the next (and final) major version: 2.0.0. This will involve some backwards-incompatible changes to the API. Many symbols (functions, methods, properties) are unnecessary and will be removed.

I will also try to fix a number of problems in a subsequent release, probably either version 1.9.1 or 1.10.0, without removals or backwards-incompatible changes.

I'll update this issue with more detail, when I have it.
