    Name        :   Lot_API

    Description :   API logic for the Lot resource.

    Notes       :   All web APIs should include the API_SETUP insert. This will provide several useful variables:

                        HTTPMethod              - The HTTP Method (Verb) submitted by the client (e.g., GET, POST, etc.)
                        APIURL                  - The URL for the API entry point (e.g., api.mysite.com/v1).
                        FullEndpointURL         - The URL submitted by the client, including query params.
                        FullEndpointURLNoQuery  - The URL submitted by the client, excluding query params.
                        EndpointSegment         - The URL endpoint segment.
                        ParentURL               - The URL path preceeding the current endpoint.
                        CurrentAPI              - The name of this stored procedure.

    Parameters  :
        API             [in] -- Web API to process. Format is [APIPattern].[HTTPMethod]:
                                    - APIPattern must follow this structure Lot[.ID.[<Property>]]
                                    - HTTPMethod can be any valid HTTP method, e.g., GET, POST, PUT, DELETE, etc.
                                Examples:
                                    - Lot.POST
                                    - Lot.ID.PUT
                                    - Lot.ID.firstName.GET
        Response       [out] -- Response to be sent back to the Controller (HTTP_MCP) or requesting procedure. Web API
                                services do not rely upon anything being returned in the response. This is what the
                                various services like SetResponseBody and SetResponseStatus services are for. A response
                                value is only helpful if the developers want to use it for debug purposes.
