clean up check selection code This new approach allows filtering out checks from the default set that are not appropriate for a command, rather than having to list every check that is appropriate. It also reduces some boilerplate. Haskell does not define Eq for functions, so I had to go a long way around with each check having a unique id. Meh. 2011-10-29 19:19:05 +00:00			`def :: [Command]`

remove command type definitions These were a mistake, they make the type signatures harder to read and less flexible. The CommandSeek, CommandStart, CommandPerform, and CommandCleanup types were a good idea, but composing them with the parameters expected is going too far. 2011-09-15 20:50:49 +00:00			`start :: CommandStart`
