How to use CLASS TEMPLATES, type traits, partial and full class template specialization

Class templates with the ability to partially and fully specialize them are arguably what makes C++ so powerful! We cover most of what one needs to know about what class templates are, how to specialize them fully or partially as well as how it all plays its role if we want to implement type traits.

In this video we look at
Class method templates
Class templates
How they can be specialized partially and fully
And as always some easy to follow examples as well as stories about what can go wrong with template specialization
We cover a lot of ground in this video, and it is quite long as much as I tried to keep it very short. Please do not hesitate to comment and tell me what you think or what I might have missed.
