 REQUIREMENTS
 
 Client
-    - Client needs to tell the server which form of list is required, i.e. it's client window size when fetching a list
-        - viewport="XS" I think would be sufficient
+    - Client needs to tell the server which form of list is required, i.e. it's client window size when fetching a list    
+		- HYBRID BIMODAL: XS or LARGE (for now but consider maybe a medium down the road in planning)
+			- in XS mode
+				- the client sends "viewport=xs" to the client with the grid data request
+				- Client receives two field list back (id and display field), displays the single field
+			- in large mode
+				- the client sends no viewport= parameter as it's optional and understood to be full size
+				- the list comes back as an object with not only the actual columns but also a separate property listing the set of columns in order to be displayed 
+                    - Also their data type 
+                    - Also need to handle links of what type of object and or ID to open maybe for each column
+					- Client expects an arbitrary set of columns in an arbitrary order defined by server so doesn't have a pre-ordained set of things.
+						- HMMM... Maybe I only need a single list object that adapts to the data being sent back
 
 Server
     - Server needs to accept a parameter from the client when a grid list is fetched that tells it if it needs to send a single column templated list 
         - viewport="XS" I think would be sufficient
     - Grid lists need to know what their template is as more than one list might use the same template?
+    - SERVER SENDS LIST OF COLUMNS
+			- The server needs to tell the client which columns are coming back with the list and what types etc so the client can just adapt to any template setting
