Metacat

Add the code to check if the existing highest uidNumber really exists.

In the getNextUidNumber method, a mechanism to look up the highest existing udiNumber was added.

Fix XML validation errors in the metacatui confirmData template for the registry. Add a test script that submits multiple datasets to the registry.

Create a lock file for the registry
if one doesn't exist

Allow the registry form to specify a docid scope

Only lock the local docid file when creating a new docid, not when inserting, for faster upload times. Remove extra debug messages from testing.

Fix bug in the online registry where data files were not using the new docid creation process

Lock a local file while docids are being created so multiple docs can be uploaded at once

remove CN.systemMetadataChanged in favor of the CN.updateSystemMetadata method. Otherwise there's no good way to know where to fetch the auth copy from since the SM change might be to switch the authMN!

add support for v2 DataONE API.
