[v0.6.1][HAPI-177] Declarative Structure Improvements

HAPI-177 Description

• The lib declarative structure was changed, now the lib has a main instance class 4HandsAPI that handles all services related to the lib.
• CRUD helpers was integrated to the DBService and now it's under database
• Services and models have a shortcut path to be called on the projects
• All services are independent now, and they can be used outside of the main instance as well.
