Planning API

Please add a public-facing API to Planning that would let us extract information, e.g. songlists for each week, filtered by service type/name or people involved...
We would look to use this to enable us to find useful statistics, such as number of new songs introduced, and reinforced, etc...

I would also like to use an api to generate an overview of the church services (e.g. for half a year) as a short list (e.g. date, preacher, moderator, teams assigned members). Currently we manage this in excel.
