extra simulations for initialisation - where are they and how documented

[bnlawrence]

We are, I think, running extra simulations to get extra ocean states for macro initialisation. Where are these simulations being stored? Are they being stored? How will we refer to them in the parent_id?

We will four or five from 1850-1950. When, who, what to name them, and where to put them. It’s the same suite, but we need to perturb the start with a different PI control dump. These are technically standard CMIP ensemble members.
