Detailed Description

template<class T>
struct KSharedPtr< T >

Can be used to control the lifetime of an object that has derived KShared. As long a someone holds a KSharedPtr on some KShared object it won't become deleted but is deleted once its reference count is 0. This struct emulates C++ pointers perfectly. So just use it like a simple C++ pointer.

KShared and KSharedPtr are preferred over QShared / QSharedPtr since they are more safe.
