Describe your feature request

Users have often mentioned the request to get the last checkpoint/config.

there is a get_best function, but a get_last would be nice.

From user:

To be honest the ExperimentAnalysis response object while it has everything I need seems to have a bit of a clunky api.

Also, it's unintuitive to default to 'all': Users might often say

If you take the max of these scores, its different from analysis.get_best_config()
