Provide Pre-Simulated Baseline for Reuse in Future ProfileSet Simulations

[cesoun]

I'm unsure if this is a feature or something anyone else has considered but I was looking at the ProfileSet Wiki Article and was wondering if there was a way or possible improvement that could be made for speeding up very large profileset simulations.

As it stands you provide the baseline definition and then any additional profileset definition(s) that you'd like to and then the baseline is simulated, followed by all the profileset(s).

The feature I am interested in would be in a scenario where the baseline is unchanged, to be able to provide a pre-simulated baseline in order to skip re-simulating the baseline again, and instead skip straight into simulating the profileset(s).

This would skip the time spent simulating the baseline again and could allow for executing multiple simulations utilizing the same baseline.

e.g.

1. Baseline is simulated
2. Baseline is written to the disk
3. N current/future simulations load the pre-simulated Baseline from the disk to use as their simulation baseline

I'd also be interested in messing around with this in my own time, assuming there is no other technical reason this couldn't be done.
