Add functions to perform table queries on AF tables

To access data on AF Tables i now need to add these to an attribute and then access these from analytics I would like to be able to create a lookup using a Analytics function, so that i can create a lookup of a value in a table based on other calculations i do within my analysis. This can be limited to the current functionaltiy in the Table Lookup DataReference. E.g. to perform forecasts, i currently create attributes where i sum values based on timestamps for x-days forward in time using analytics. Then i use these attributes again in another analysis that performs the forecasting calculation. To be able to query a table directly, i can include all logic within the Analysis
