[Bf-taskforce25] data api proposal

[Brecht Van Lommel]

Hi,

Made some changes, and added a bit of text on IPO's. Haven't written 
too much about it since I'm not very familiar with the issues there, 
but I don't foresee many difficult issues, only thing I wonder about 
is how to identify the property best (unique ID, name, ..).

Renamed list -> collection, added modify(), and a bunch of other changes.

The reason I mentioned strings is that they can be variable length. 
Though of course ID names for example have fixed length. I think a 
function that gives a pointer + maxlength, and another function to 
retrieve the length should work.

Both thanks for the feedback,

Brecht.
