Properties and methods specific to the Scriptel STSeriesDeviceContainerDevice signature capture DeviceContainer. This class is not a typical implementation of STSeriesDevice. It was created solely to support languages that cannot cast between super and subclasses, and need to always get a concrete implementation. Specifically VB6 could not handle getting passed a STSeriesDevice from the STSeriesDevicesManager. It needed to be passed a ST1500 or ST1400 etc. The need for separate code for each device type creates much duplication. This class was created to "wrap" any STSeriesDevice so VB6 could can always expect to get a STSeriesDeviceContainerDevice, regardless of the actual attached device. All calls made to STSeriesDeviceContainerDevice are passed to the wrapped device, and all events from the wrapped device are refired by the DeviceContainer
