A simple degree/minutes(fractions) add/subtract calculator.
This is written for celestial navigation using tables, so the requirements are
- only add/subtract
- minutes as fractions
It was also for me to experiment with and try learning some Swift and SwiftUI.
Todo
- unit tests for DegreeCore
- unit tests for ModelData's functions
- treat op without input as ANS
Bugs
- disallow > 3 ints for degrees when typing
- if entering 600'0, it displays 0d00'0 instead of 10d00'0
