mwrap 2.0.0
This release includes significant changes to track live
allocations and frees.  It can find memory leaks from malloc
with less overhead than valgrind's leakchecker and there is a
new Rack endpoint (MwrapRack) which can display live allocation
stats.

API additions:

* Mwrap#[] - https://80x24.org/mwrap/Mwrap.html#method-c-5B-5D
* Mwrap::SourceLocation - https://80x24.org/mwrap/Mwrap/SourceLocation.html
* MwrapRack - https://80x24.org/mwrap/MwrapRack.html

Incompatible changes:

* Mwrap.clear now an alias to Mwrap.reset; as it's unsafe
  to implement the new Mwrap#[] API otherwise:
