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.
