NOTE: The paper "A Unified Theory of Garbage Collection" was already
present in the garbage collection section, so I just added a brief
summary.
Removed newline between papers
Removed Ctrl+M in previous title
Some combination of markdown and GitHub don't support creating links
to ftp servers, so I'm including a copy of the paper and presenting
the URL to the paper as text instead of a link.
Rather than artificially separate garbage collection from other classes
of memory management, I propose moving garbage collection topics under
the more general label of memory management ("storage management" or
"memory allocation" might be reasonable alternatives).
