This class allows you to create shared memory objects easily. A shared memory segment is a chunk of memory that is shared between multiple processes in a system.
Shared memory is great for things like holding status information.
For example, you could have a process that reads position information from a GPS unit and puts it into shared memory. You could have many other applications connect to that shared memory and read the position data. Data Members None. Closes the object. You can no longer use the pointer.
