Removed unused property of shouldFeelLike

Removed unused prop from playGround as I figure out what I actually
need to define and what I don’t.
First commit of prototype app project

Full expecting to rip this apart, but as of now, can at least
initialize with values, do calculations and populate labels and fields.
Initial tip functionality

Works on calculate button.
Removed calc button, live updating
Cleaned up keyboard dismissal method
Simplified field change updating behavior
Removed unused calc button outlet
First try moving to country model. Not quite there.
Working country models, sort of, with US based exchange rates
example using the model to reset UI to norway/usa
Added precision for more easily parseable home currency display
Removing extraneous UI in advance of implementing picker
populated pickers with names
simplified down to just nok / usd UI

next steps are to figure out how to easily choose, retrieve, and update
the math using the valuse stores in countries.plist (or otherwise)
Simplified UI upates
Removed reset function, added update countries function
Adding precisoin to plist, trying to figure out models still
trying to figure out why i can't update countries
Using updateCountries method, still can't pass Countries to it

can now switch from norwegian to euro (not back)
oh a norway button why not
