Fixes these bugs, too: - Polygon's simplify method didn't square the tolerance parameter when it should have - Polygon's 'highestQuality = false' didn't work at all(!)
Also removes hard-coded test which had wrong values
Also fix compiling using .xcodeproj file

This is ready for review. It runs fine locally and the tests pass. I can't access the bitrise issue for tvOS, so if someone can point me at what's wrong, I'm happy to investigate. |

This branch fixes these issues introduced in the port of turf-simplify from #138:
LineString.simplifywithhighestQuality = falsewas broken as it was usingstart.coordinatein one formula when it should have usedcoordinatePolygon.simplifyignoredhighestQuality = falseas it first assigned theself.coordinatesto a local variable, then simplified theself.coordinates, but then passed the previous local variable to the Douglas-Peucker algorithm. That means it always returned results as ifhighestQuality = truewas set.Polygon.simplifyforgot to square the tolerance to the Douglas-Peucker algorithm (LineString.simplifydid it correctly)Polygon.simplifydidn't simplify if any of the exterior/interior polygons was a triangle; now it just skips simplification of the triangle but simplifies the others.I've also refactored the code to remove the code duplication between
LineString.swiftandPolygon.swift, and ported the turf-simplify test suite using the in/out directory -- excluding the test cases for MultiLineString and MultiPolygon as they aren't supported yet.TODO:
