0.3

v0.3: This release is much polished compared to 0.2, and suitable for
even broader use.

  Tickets closed because they were in the roadmap:

  14: Any State + Any Event = Maybe Semantic Pass Failure.
  17: Exit functions are generated for terminal states.
  27: Better error messages
  32: Transient state @function prototypes
  33: _ [ _ -- ]
  34: Clean up release target.

  Tickets closed because we felt like it:

  18: _ event in _ state.
  31: Expose a way to get internal state?
  35: Separate object directories
  36: Option to disable no-transition events in dot output
  41: Debug code takes up global memory.
  50: --output-path=PATH

  Tickets deferred to 0.4:

  15: Typed function calls not implemented.
