Renaming classes

The first step would be to rename the classes and enums so they don't expose this ugly FV prefix:

typedef NS_ENUM(NSInteger, FVMeasureUnit) {
 /* ... */
} NS_SWIFT_NAME(MeasureUnit); // notice the attribute is 'after'

// And for interfaces the attribute is before
NS_SWIFT_NAME(Measure)
@interface FVMeasure : NSObject

We can now rewrite our Swift to the following:

let measure = Measure(amount: 10, unit: MeasureUnit.cups)

The class and enum names are quite better but we can go further.
