Changeset 863 for branches/prototype-v0/zoo-project/zoo-services/ogr/base-vect-ops-py/cgi-env/ogr_sp.py

Message:

Change the default ZOO-Kernel behavior, if an input has been passed by reference, the ZOO-Service will receive a cache_file map rather than the value field which was usually returned, same for array value apply. To use the previous behavior, one can add "memory=load" to the main section of the main.cfg file. Update ZOO-Services for using this new field if available.
