added weight property to workout entries and integrated it into the workout entry view controllers
started on the workout log tab
I need to be able to sort workout entries by date so that they appear in the correct order in the workout log tab, so I added sorting code to WorkoutLogStore
workoutlogstore now sorts entries by date
- store has a class method to sort an array of workout entries into arrays by date, and returns all of the arrays in a larger array
entries show up in log
- filled in data for log tab, added view in storyboard to edit entries
