+ 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.
+ Add documentation and examples.
+ Add new functions to interact with the framework:
+ spec.eval - eval a function by name and echo its description field
+ spec.functions - prints functions currently in scope that match the key glob
+ spec.log - log a message / test result
+ spec.run - run suite of tests
+ Rename list.erase to erase.
