import io_services into flicker.py.

I, also, removed the load_data function. This is part of the gradual
move to transfer 'service' based functions out of flicker.py. The aim
here is to reduce the need for duplicating code or make it easier to
make function calls when needing a particular piece of data (or
transformation of data).
