In profiles, attributes are set with an AttributeTable at the profile level. Then, every internal object has an AttributeIndices attribute which holds references to the main table.

This means components need an additional step to modify the attributes (add, remove them). So we should provide an helper method to facilitate the action and make it efficient all the time.

We could have something like:

ToAttributeIndices(data pcommon.Map, table AttributeTable, record attributable)

Which would do a full replace of the attributes with a new map.
However, folks would have to first get the attributes and then update them to make a single update.

We could also have a single attribute add:

Addattribute(key, value string, table AttributeTable, record attributable)
