use attributes for complex objects
A nasty exception for prefLabel in attr proxy << review
return [] not nil on defined empty attributes.
return [] when attr is loaded and it is nil in .find calls.
lazy load on find.
Do not load inverse properties as defined.
removed transient_attributes in goo
return the send message in lazy load
useless if out
test for pagination
fixed tests. change in order results.
dependent objects preloaded point to Resources.
recover sort on search if not pagination.
try/catch as fallback for integrity constraints.
do not do order when counting
bnodes should be preloaded as well.
Merge branch 'master' into search_skeleton
embed objects for retrieval in page/where/find
where/page accept :attr => unbound
extra filter from model
