bootdht and dht2 incompatibility

[erex]

For analyses requiring dht2, e.g. non-geographic stratification or multipliers (not using the activity package, bootstrapping cannot be performed.

This is because bootdht only accepts as input dsmodel objects, not the sort of objects created by dht2

@erex does this need to be resolved by a particular date? Is there an issue when using the activity package?

[erex]

No, no date. It should either be fixed (so the two functions are compatible) or there should be documentation to indicate (or test for) circumstances where a dsmodel object will cause dht2 to choke.
