Flex workbench

[isangil]

The designed workbench workflow is really nice for groups that want to establish a chain-of-command, or quality control checks. As a DEIMS user, you can enter a dataset, save it, but not publish it. The admin has to publish the datasets later.

This, without much documentation, may create confusion.

I propose we make the whole Workbench stack optional, or at least document it well.
