PPBKA3M-77 - Create IDatabaseAccess
This interface represents the API that both the CLI and web apps will use to access the database.
Also implements the skeleton of domain objects necessary for the IDatabaseAccess interface.
Since this is the first commit performed from Visual Studio, it contains some changes to the solution, project, and .editorconfig files that Visual Studio made to conform to its expectations.
Closes PPBKA3M-77.
