Accept any value, store its Ruby truth value (excepting another instance of this class, where use its {#value}).

So new(0).value is true. @param value [::Object,DBus::Data::Boolean]

Calls superclass method DBus::Data::Base::new

    # File lib/dbus/data.rb
235 def initialize(value)
236   value = value.value if value.is_a?(self.class)
237   super(value ? true : false)
