Detailed Description

Class that represents a north plugin.

The purpose of this class is to hide the use of the pointers into the dynamically loaded plugin and wrap the interface into a class that can be used directly in the north subsystem.

This is achieved by having a set of private member variables which are the pointers to the functions in the plugin, and a set of public methods that will call these functions via the function pointers.
