Preparing to bring some testing modules into the Dao system for general use.
Created a Prelude for the Dao system, which is really intended to be used from GHCi, but should also be useful from other programs that wish to import the Dao system.
Moved the random object generator from the set of tests into the main Dao package.
Cleaned-up all the recent changes, put the source code back into a state where it can be built properly again.
