+ Add fish eval fix See #fish-shell/pull/1892
+ New and improved output system with colors, etc.
+ Support for multiple non-nested describe blocks.
+ Remove spec.log and favor `msg` plugin and standard echo.
+ `spec.eval` no longer evaluates multiple functions, acting now as a simplified
router between the view `spec.view` and the controller `spec.run`.
+ Add new `spec.view` to act as a hub for all test output.
+ Add report with passed/failed tests to `spec.view`
+ Now test descriptions are used directly from the function name. Description
fields are now optional.
