Detailed Description

template<typename T>
class tgSubject< T >

A mixin base class for the subject in the observer design pattern. Observers are attached to the subject, and their onStep() member functions are called when notification is required. Used primarily for control of tensegrity structures, a structure that needs to be controlled will be a child of this class. This can either be the main model or submodels such as a tgLinearString
