Creating a source generator (#19)

* First NuGet Release (#16)

* Added NuGet publish

* Updated to only deploy when release is merged

* Separating publish step

* Added release to build process on PR

* #12 FINALLY got the source generator to work

* #12 YES!! The source generator is working!

* #12 got the parsing methods working

* #12 added more tests

* #12 added support for key attribute

* #12 added some comment notes on how to use the source generator in the web app

* #12 removed some code for key attributes that's no longer used

* #12 added a way to do configuration

* #12 made progress on the new approach that has configuration. Tests need to be reworked, but it seems promising

* #12 hey, it works in the WorkingApi project!

* #12 all tests pass now

* #12 got all the API verbs in now

* #12 changed "db.Set<tableType>" to "db.{propertyName}"

* #12 very minor code ordering change

* Publishing release with new JSON APIs (#44)

* Added video demo

* adding JSON Mock API

* adding instructions

* Added HTTP Results calls to fix #7

* Added configuration for JSON APIs

* Tagging for a preview release

* Added Release Notes file

* Moved release notes to top level

* #12 updated to IEndpointRouteBuilder

* #12 got the APIs to return the "right" thing

* #12 confirmed new changes work in API app

* #12 NICE! Just updated config for SG, initial results are good, added a separate WorkingApi.Generators project to run the SG in its own project.

* #12 updated configuration to take an Action<Builder>, makes it more similiar to the Reflection approach

* #12 fixed an issue with ignoring Included value

* #12 started working on logging, tests WILL break right now

* #12 logging is in, all tests pass now.

* #12 added an attribute approach to define which DbContext classes should be mapped

* #12 got all tests for the SG approach in (for now)
