For several versions, VTK-m has had a `Variant` templated class. This acts like a templated union where the object will store one of a list of types specified as the template arguments. (There are actually 2 versions for the control and execution environments, respectively.) Because this is a complex class that required several iterations to work through performance and compiler issues, `Variant` was placed in the `internal` namespace to avoid complications with backward compatibility. However, the class has been stable for a while, so let us expose this helpful tool for wider use.
