Awesome.

Two thoughts:
1. The fact that keyword arguments with a default of None are allowed to be passed as positional arguments is a bit of a Python wart that I usually like to avoid. ('def get_value(self, key, startkey=None, endkey=None...)`... `get_value(key, startkey, endkey)`.)  Since you're not doing anything with key, startkey, endkey, couch_view, or db, why not just pass them through with `**kwargs`?

2. I'd like to think of this submodule as a generic tool that someone using couchdbkit in a different problem-space might use.  Not primarily because I actually expect that, but because maintaining abstraction barriers promotes good code.  To that end, "Indicator" might not be an appropriately generic word here.  I have some ideas about possibly making this more generic that I'll try to push to this branch soon and see if you like them.
