Detailed Description

Process Controller for D2 Process This class is the DHCP-DDNS specific derivation of DControllerBase.

It creates and manages an instance of the DHCP-DDNS application process, D2Process.

Todo:: Currently, this class provides only the minimum required specialized behavior to run the DHCP-DDNS service. It may very well expand as the service implementation evolves. Some thought was given to making DControllerBase a templated class but the labor savings versus the potential number of virtual methods which may be overridden didn't seem worth the clutter at this point.
