Successfully pull some reward data
Changed reward model to fit with ember's extremely annoying model binding
Renamed controller to handle everything (simplify.)
Copied tasks api calls to rewards
Redeeming reward updates wallet.  Changed wallet PUT to look by wallet ID because ember says so.
redeeming reward also deletes reward from database
Wiring front to back

The tasks are creatd and deleted proeprly. The wallet is updated
