CnC context bringing together collections (for steps, items and tags).
The user needs to derive his or her own context from the CnC::context. The template argument to context is the user's context class itself.
For example,
Several contexts can be created and executed simultaneously.
Execution starts as soon as a step(-instance) is prescribed through putting a tag. All ready steps will be executed even if CnC::context::wait() is never be called.
It is recommended to declare collections as members of a context derived from CnC::context. This yields more maintanable code and future versions of CnC may require this convention.
