* TODO
* 1) add database functionality for persistent pill list -
* 2) add remove pill button fucntionality for if a pill is no longer needed - DONE
* 3) clean up UI -
* 4) add error handling - DONE
* 5) check for interactions between pills
* 6) get info about a specified pill
* 7) CONSIDER: one pill with multiple times a day eg - one in morning one at night not taking up 2 spots
* this would prevent pill 1 at 2 and turn into pill 1 at 2, 3 and adding only pill 1 at 2 or pill 1 at 3
* pill 1 at 3
