Infrastructure

We divided the implementation into two phases:

Phase 1: Work with multiple MNs, but choose one as active MN for create(). Morpho still uses Metacat API to search
User selects 'Active' Member node from dropdown list in settings; list generated from Node service; or enter baseurl
If MN is metacat, use metacat API to search
** Metacat search API only returns metacat docids (scope.docid.rev) not the DataONE PIDs
** Issue: how to get ahold of the PID rather than the localID so get()/create()/update() can be called
If MN is not metacat, disable network search, only allow local open
For create
Create on the active MN, set authMN to the active node id
For update/delete

If a user has rights to call update/delete on the AuthNode, and a write permission on an object, they can update/delete on the authNode
-- 3 checks have to pass: userHasWrite on object, user has execute on service, and authMN is available for object
If authMN is not available, don't do update()

Phase 2: Use dataone API to search
Some issues need to be addressed:
Will Morpho search CN, MN or both? If search MN, we need an optional search API for MN.
If we only search CN, we need to deal with the variable sync lag times on CNs
Need a search mechanism to include metadata fields in CN/MN
