Description

Cannot create a Android.Gms.Fitness.FitnessOptions.Builder instance because FitnessOptions.Builder' does not contain a constructor that takes 0 arguments

Steps to Reproduce

1. Write the following code

   var fitnessApiOptions = new FitnessOptions.Builder()
               .AddDataType(Android.Gms.Fitness.Data.DataType.AggregateActivitySummary, FitnessOptions.AccessWrite)
               .AddDataType(Android.Gms.Fitness.Data.DataType.AggregateSpeedSummary, FitnessOptions.AccessWrite)
               .Build();

2. Observe that the error in the description appears on compile

It seems that creating the builder has to be done through the InvokeBuilder() method on the FitnessOptions class.

Changed the code to

            var fitnessApiOptions = FitnessOptions.InvokeBuilder()
                .AddDataType(Android.Gms.Fitness.Data.DataType.AggregateActivitySummary, FitnessOptions.AccessWrite)
                .AddDataType(Android.Gms.Fitness.Data.DataType.AggregateSpeedSummary, FitnessOptions.AccessWrite)
                .Build();

and the FitnessOptions are created.

I'll keep the issue open because documentation is poor, and I would expect the mapped classes to behave like their java counterparts.
