Image link in README should no longer trigger 'insecure content' warnings,
the link was reading from a non-HTTPS source.
Other rewordings and minor refactors
Changed the wording of some sections. Added more info to some of the
exercise README files.
Added some more structure to the tests exercise to make it a little
less open. Still undefined sections but there is a bit more guidance
about what things might look like.
Preparation for the name change to 'Applied' instead of 'Advanced'
Readme install and setup instructions improved. Added note about course being
designed for use in a guided environment. Made the FUTURE_PLANS a little less
self-interested.
Level 07 contains the addition of the ExceptT transformer for error handling in
the existing AppM from Level 06. Extends teh AppM to the DB layer.
Updated README with status
Don't need the extra status declarations for some of the Hspec tests
at level04 as hspec-wai assumes 200 until told otherwise.
Removed Hedgehog from level04 tests, don't have a good use case.
Level 04 contains some testing fun.
Removed spurious yaml file from level03.
Update README.
Have noticed irritating snafu RE the app structure. Not built as a
library in other levels, will fix.
Level 01 : Absolute Starting Point
- possibly too basic
Level 02 : Start specifying an application and filling it out
- needs more detail about the spec we're trying to build
README adjustments.
