Allow a user to provide their own data frame

[da-crivelli]

In some cases, a user might want to exclude certain results or provide a non-grid type set of data points.

The workflow could be as follows:

• User runs a dry run and obtains a blank dataframe
• User manipulate data frame
• User calls the analysis with a user provided dataframe

OR

• user has an existing dataset or an analysis that needs resuming / refining
• user sets an additional "recalculate" column to true/false
• parametric only runs cases where recalculate==true
