* Created performance tests to compare Vuckt's `Float3` performance to Swift `simd.float`'s to `GLKVector3` to C/Obj-C `simd_float3`. * Added new `VucktPerformanceTests.swift` and `VucktCPerformanceTests.m` to Xcode project & SPM package. * Minor: Removed old placeholder `testPerformanceExample()`.
