* Removed Tenanting from base objects as some models may be tenantless
* Admins are naturally not restricted by tenants
* Users *ARE* the tenants (for now) so they don't require a tenant ID
either
* User-owned models should all include the Tenanted model as their base
* Created .Create and .Save methods attached to base model
* Signup -> Login -> JWT-Doot flow now works for users
* Administrators cannot currently sign up for obvious reasons
* Segmented the main.go methods into a core controller package
* Created Base, Auth, User and Admin models
* Added skeleton API structure containing: User signup, User & Admin
login, authorized zones, ping tests
* Simple user signup functional
* Skeleton user login functional, no means to verify as of yet
* Added POSTMAN file
