Added org taking access to Surveys.
This taking access means that everyone with an active role for any organization for a given program can take the Survey. This will allow one Survey to be taken by both Org Admins and Mentors.
indexes:
# AUTOGENERATED
# This index.yaml is automatically updated whenever the dev_appserver
# detects that a new type of query is run. If you want to manage the
# index.yaml file manually, remove the above marker line (the line
# saying "# AUTOGENERATED"). If you want to manage some indexes
# manually, move them above the marker line. The index.yaml file is
# automatically uploaded to the admin console when you next deploy
# your application using appcfg.py.
