memory: Hide all copy/assignment ops for class w/heap allocation

Many of the UPM libraries allocate space on the heap but do not
explicitly handle copying and assignment.  This commit uses C++11 delete
to forbit both the copy and assignment operator for these classes.

The C++ examples which used assignment operators to initialize class
instances were also updated since it did not appear necessary in those
cases to use the assignment operator.
