Expected behavior

We only need to select one cohort by default when opening the Cohort Characterization results.

Actual behavior

In my example, I have 120 cohorts in my characterization, leading to a very long load time as all the cohort data is returned and processed on the client.

Steps to reproduce behavior

1. Create a CC with 120 cohorts
2. Generate CC
3. Open Results
4. Have fun clicking 119 times to narrow the results down to 1 cohort (I think we need a select all/deselect all button).
