Base class for representing a database source.

This is the class to inherit from when you want to create a general class to represent a specific type of database source (ie. CGI scripts). When deriving, you must implement the _rawget() function which takes a list of parameters and returns results. These results might be a handle or any other kind of result. You can optionally derive from _post_process() to do any sort of clean-up on the data.

(XXX This should return a SeqFeature object, me thinks, and only a handle if you don't know how to parse the results that come back. Or something like that.)
