0.7

v0.7: First release as a part of Splat: the Smudge Platform.

  Project:

  The Smudge language now has a distribution, Splat, including both
  the Smudge compiler and the Smear environment and runtime.

  Oh yeah, the Smudge language also now has an official runtime: Smear!
  The compiler supports generating bindings using the `--c-smear` flag.

  Features:

  The biggest minor feature is that event cycles are detected and
  rejected.  Yes, that's right, Smudge solves (a tiny subset of) the
  halting problem.  It is pretty conservative; it rejects machines
  unless it can tell that all messages sent to an empty queue halts.

  Errata:

  Smudge now generates code that no longer yields an unused parameter
  warning.  This means that all Smudge output compiles silently with:

  gcc -c -std=c89 -pedantic -Wall -Wextra -Werror -Wno-unused-function

  Additionally, there were several errors that were discovered using
  code gen; most of these have been fixed.

  Tickets:

  21: Reject event cycles.
  43: A single state can't handle an event two different ways.
  58: Detect undeclared events sent to other state machines.
  61: Any cannot be transient
  62: Vim mis-highlights parenthesis in name.
  67: Forbid nonsensical any states
  73: Boolean command line switches should be invertable.:
