Implementation description

• Two valid formatted camps - 63538bc01bf0453b8a55ea1a and 63538da50ec7fc7b4a841085, and sample camp session data to add

Usage

• Use however needed, can POST into the appropriate endpoint
• Also nice to cherry-pick and reset --hard HEAD~1 commands onto current branch if you want it temporarily

Useful list:

• Create sessions: POST localhost:5000/camp/:camp_id/session
• Create camp: POST localhost:5000/camp, use form-data with "data" key -> see feat: camp model update #62
• Create campers: POST localhost:5000/campers/register, raw json but warp in []
