pluggable helpers

[mvexel]

I kind of like the idea of introducing pluggable helpers to extend the functionality of this module. Think of them as pre-cooked queries for specific purposes. The existing MapQuery and WayQuery are simple examples. However I would want the architecture to be such that anyone could contribute helpers easily by adding a .py file to some directory. Who wants to help with (thinking about) this?

Keeping this open as an idea.. I still like it and would love to discuss as a future enhancement.
