* It works?
* Add multiple return values back in
* Allow order by alias
* Support groupBy and count, Returning value from a fromQuery now will make it into an alias
* Eliminate Alias type, TODO: finish implementing all the functions on Value for the alias constructors
* Add entity support to subqueries
* Cleanup duplication; Cleanup warnings and finish implementing all the cases for aliased values and entities.
* Cleanup fromQuery and add comments
* Modify EValueReference to support aliased entity fields instead of having to use opaque ERaw in field access
* Implement SQL Set Operations
* Add test to show novel use of fromQuery
* Cleanup unsafe case statements
* Add type annotations to helper queries to satisfy the typechecker on older GHC
* New syntax for joins, using placeholder names with ' in them to avoid name conflict with existing join types.
New api properly enforces Maybe on outer joins and requires an on clause for all joins in their construction.
* Add some more test queries using the new syntax
* Add test to verify that delete works with the new syntax
* Add cross join and implicit cross join using comma examples to test code for new from syntax
* Comment out use of CrossJoin in common tests since postgres cant handle it with the current implementation of the CrossJoin kind
* Add typeclass machinery to support the use of the old Join data types used in the existing from clause
* Fix bug with CrossJoin and add on_ syntax sugar
* move new from syntax into Database.Esqueleto.Experimental
* Merge subqueries and unions with the new join syntax, they all seem to play nicely together
* Cleanup somehow copies of ToAlias ended up staying in Internal and a swp file made it in to the branch.
* Fix compilation errors
* Swith tuple to using a TypeOperator
* Make operator only 2 characters
* added up to 8-tuple instances for ToMaybe, ToAlias, and ToAliasReference
* Add compiler error tests for new syntax to support making better errors
* Use closed data families to allow for catching missing on statements in joins.
* Convert ToAliasReferenceT to be a closed type family matching the other classes in the Experimental module
* added Esqueleto.Experimental documentation: added introduction and several examples of old vs. new syntax
* added more usage examples to module introduction; added documentation to SqlSetOperation, From, on, from, and (:&)
* Update (^.) to only treat natural keys with more than one component as ECompositeKey. Fixes#176.
* Update article metadata test to ensure the correct response was being returned instead of just check if an exception was thrown
* Add article metadata to cleanDB before deleting all articles to fix foreign key constraint errors
* Bump version number and add changelog entry
* Fix issue with ToMaybeT for Values, Maybe was going in the wrong place compared to the rest of the library. Add test to prove that Left joining into a subquery that returns a maybe flattens the maybe properly to avoid needing to call joinV.
* Fix common test for postgres, needed to add dogCounts to the group by since postgres is strict on only agregates for non grouped columns; I really need to set up a local postgresql
* Revert ToFromT changes. Only accept functions that return a SqlExpr (Value Bool) in ToFromT
* escaped use of '@' in TypeApplications in documentation
* Add more specific type signature to `on`
per parsonsmatt review suggestion. Improves type inference significantly.
