PR 484882

a request:

we can pull some code and results out of the drmem test suite.

I should also add the examples from my Tech Talk slides to the docs

Server: perforce-panda.eng.vmware.com:1985

• added a simple example of an unaddressable error with a diagram. I'd like to add more examples and more diagrams, including from my Tech Talk: this is just a simple step in that direction.
• mentioned std::string and heuristic disabling runtime options for leaks
