Variants

Variants are implemented in DBus-cxx as their own class, Variant. Variants are type-safe unions that can contain a single type in them.

As of version 2.5.0, variants should be able to be nested to an arbitrary depth.

There are some limitations with Variants with how DBus-cxx implements variants:

Variants are immutable Variants as they are currently implemented are immutable and cannot be changed once they are created. If you need to change the value, you must create a new variant.
