Fetches an array of Day objects, sorted by date
Note
Currently fetches ALL days, then filters in ViewControllerHealth to last 7/30/60. This is due to Day.date being astring
not a Date, and therefore not being filterable using a fetch predicate. Ideally this would be refactored for efficiency when many Days are stored, but even within several years, it is unlikely to have much effect on performance.Declaration

func fetchDay() -> [Day]Return Value
Array of Day objects sorted by date or an empty array if no Day objects exist
