[FEAT-Roadmap]: Create Incremental assumption analysis functionality

I received two major use cases in the form of user stories. We want to make sure our workflow design would be compatible to these two use cases.

Title: Incremental assumption analysis
User Story:
As a modeler, I want replicate past simulation runs sometimes with small changes to the inputs or assumptions so that I can do incremental analysis by evaluating the change between each simulation.
Notes:
Modeling is inherently an iterative process, your first simulation is probably not going to be the one that you need. It is very often the case that you do a run, saw that something is wrong, change one of the assumption or underlying data, then rerun. We want to make the comparison between the two modeling runs as easy as possible as to identify the incremental difference between the two. If you think of a side-to-side comparison, then you got the right idea.

The issue names no files, tests, or entry points. Start by reviewing the existing workflow design and how simulation runs, inputs, and assumptions are represented, then clarify the scope and acceptance criteria for comparing two runs with incremental changes. Done should be defined by an agreed design and workflow for the stated user story.
