Computed properties

[rwb27]

This is the start of computed properties. Computed properties are like functional properties, but they keep track of attribute access. This should then allow us to update them whenever their inputs change.

Currently, an error is thrown if anything other than an observable property is accessed.

Once this is better-tested, we need logic to:

• Call the computed property at the right time, to initialise its dependencies.
• Automatically recompute it when those dependencies change.
