implements the Deleter concept of shared_ptr without deleting anything
If you allocate an object on the stack, but want to pass it to a class or function as a shared_ptr, you can use this deleter to avoid accidental deletion of the stack-allocated object.
For convenience we provide two free functions to create a shared_ptr from a stack-allocated object (
1) Convert a stack-allocated object to a shared_ptr:
2) Convert a stack-allocated object to a std::shared_ptr of a base class

Create a shared_ptr for a stack-allocated object.
Usage:
The std::shared_ptr
points to the object on the stack, but its deleter is set to an instance of null_deleter
so that nothing happens when the shared_ptr
is destroyed.
