Providing these types tends to "lock in" the precision of the algorithms used in VTK-m. Since we are using templating anyway, our templates should be generic enough to handle difference precision in the data. Usually the appropriate type can be determined by the data provided. In the case where there is no hint on the precision of data to use (for example, in the code that provides coordinates for uniform data), there is a vtkm::FloatDefault.
