naming of data-section

[janbrouwer]

We had a discussion some time ago about the "data" section in IFCJSON, and if it was necessary.
I believe we made the choice that it was optional for snippets and transactional exchanges, but is needed when header data is present.
I think we need to pick a definitive one before it gets difficult to change.
Options:

• data; like is done in STEP
• objects; very general
• features; like is done in GeoJSON, good example, but not a good choice here because it refers more to "landschape-features"
• entities; currently my favorite, because every object in this list is defined as "entity" in the IFC schema
• any others?

no particular preference really. Except for features, which I think is really a geospatial term.
