Data subproject

This is meant to isolate all of the db transactions within the app, regardless of deployment type or decided archetecture

Post Decider Types:

1. Random: Random
   • Needs only one decider model
2. Popularity: Steps based off of reddit points
   • Needs one decider model per link
   • visits with referrals will be parsed and will try to attach the reddit post to the modulario post
   • two reddit posts should be able to visit the link with different results
3. Altering
   • Based on points, do something different idk

The Decider

post -> []decider

if only one, it's probably random, but the decider will know

If more than one, iterate through and build a closure to evaluate the decision
